Pasted from Wikipedia: Bell-Boeing V-22 Osprey

• • • • •

The Bell-Boeing V-22 Osprey is a multi-mission, military, tiltrotor aircraft with both a vertical takeoff and landing (VTOL), and short takeoff and landing (STOL) capability. It is designed to combine the functionality of a conventional helicopter with the long-range, high-speed cruise performance of a turboprop aircraft.

The V-22 originated from the U.S. Department of Defense Joint-service Vertical take-off/landing Experimental (JVX) aircraft program started in 1981. It was developed jointly by the Bell Helicopter, and Boeing Helicopters team, known as Bell Boeing, which produce the aircraft.[4] The V-22 first flew in 1989, and began years of flight testing and design alterations.

The United States Marine Corps began crew training for the Osprey in 2000, and fielded it in 2007. The Osprey’s other operator, the U.S. Air Force fielded their version of the tiltrotor in 2009. Since entering service with the U.S. Marine Corps and Air Force, the Osprey has been deployed for combat operations in Iraq and Afghanistan.

Early development

The failure of the Iran hostage rescue mission in 1980 demonstrated to the United States military a need[5] for "a new type of aircraft, that could not only take off and land vertically but also could carry combat troops, and do so at speed."[6] The U.S. Department of Defense began the Joint-service Vertical take-off/landing Experimental (JVX) aircraft program in 1981, under U.S. Army leadership. Later the U.S. Navy/Marine Corps took the lead.[7][8] The JVX combined requirements from the Marine Corps, Air Force, Army and Navy.[9][10] A request for proposals (RFP) was issued in December 1982 for JVX preliminary design work. Interest in the program was expressed by Aérospatiale, Bell Helicopter, Boeing Vertol, Grumman, Lockheed, and Westland. The DoD pushed for contractors to form teams. Bell partnered with Boeing Vertol. The Bell Boeing team submitted a proposal for a enlarged version of the Bell XV-15 prototype on 17 February 1983. This was the only proposal received and a preliminary design contract was awarded on 26 April 1983.[11][12]

The JVX aircraft was designated V-22 Osprey on 15 January 1985; by March that same year the first six prototypes were being produced, and Boeing Vertol was expanded to deal with the project workload.[13][14] Work has been split evenly between Bell and Boeing. Bell Helicopter manufactures and integrates the wing, nacelles, rotors, drive system, tail surfaces, and aft ramp, as well as integrates the Rolls-Royce engines and performs final assembly. Boeing Helicopters manufactures and integrates the fuselage, cockpit, avionics, and flight controls.[4][15] The USMC variant of the Osprey received the MV-22 designation and the Air Force variant received CV-22; reversed from normal procedure to prevent Marine Ospreys from having a conflicting designation with aircraft carriers (CV).[16] Full-scale development of the V-22 tilt-rotor aircraft began in 1986.[2] On 3 May 1986 the Bell-Boeing partnership was awarded a .714 billion contract for V-22 aircraft by the Navy, thus at this point the project had acquisition plans with all four arms of the U.S. military.[17]

The first V-22 was rolled out with significant media attention in May 1988.[18][19] However the project suffered several political blows. Firstly in the same year, the Army left the program, citing a need to focus its budget on more immediate aviation programs.[20] The project also faced considerable dialogue in the Senate, surviving two votes that both could have resulted in cancellation.[21][22] Despite the Senate’s decision, the Department of Defense instructed the Navy not to spend more money on the Osprey.[23] At the same time, the Bush administration sought the cancellation of the project.[23]

Flight testing and design changes

The first of six MV-22 prototypes first flew on 19 March 1989 in the helicopter mode,[24] and on 14 September 1989 as a fixed-wing plane.[25] The third and fourth prototypes successfully completed the Osprey’s first Sea Trials on the USS Wasp in December 1990.[26] However, the fourth and fifth prototypes crashed in 1991-92.[27] Flight tests were resumed in August 1993 after changes were incorporated in the prototypes.[2] From October 1992 until April 1993, Bell and Boeing redesigned the V-22 to reduce empty weight, simplify manufacture and reduce production costs. This redesigned version became the B-model.[28]

Flight testing of four full-scale development V-22s began in early 1997 when the first pre-production V-22 was delivered to the Naval Air Warfare Test Center, Naval Air Station Patuxent River, Maryland. The first EMD flight took place on 5 February 1997. The first of four low rate initial production aircraft, ordered on 28 April 1997, was delivered on 27 May 1999. Osprey number 10 completed the program’s second Sea Trials, this time from the USS Saipan in January 1999.[2] During external load testing in April 1999, Boeing used a V-22 to lift and transport the M777 howitzer.[29] In 2000, Boeing announced that the V-22 would be fitted with a nose-mounted GAU-19 Gatling gun,[30] but the GAU-19 gun was later canceled.[31]

In 2000, there were two further fatal crashes, killing a total of 19 Marines, and the production was again halted while the cause of these crashes was investigated and various parts were redesigned.[32] The V-22 completed its final operational evaluation in June 2005. The evaluation was deemed successful; events included long range deployments, high altitude, desert and shipboard operations. The problems identified in various accidents had been addressed.[33]


The V-22’s development process has been long and controversial, partly due to its large cost increases.[34] When the development budget, first planned for .5 billion in 1986, increased to a projected billion in 1988, then-Defense Secretary Dick Cheney tried to zero out its funding. He was eventually overruled by Congress.[32] As of 2008, billion have been spent on the Osprey program and another .2 billion will be required to complete planned production numbers by the end of the program.[2]

The V-22 squadron’s former commander at Marine Corps Air Station New River, Lt. Colonel Odin Lieberman, was relieved of duty in 2001 after allegations that he instructed his unit that they needed to falsify maintenance records to make the plane appear more reliable.[2][35] Three officers were later implicated in the falsification scandal.[34]

The aircraft is incapable of autorotation, and is therefore unable to land safely in helicopter mode if both engines fail. A director of the Pentagon’s testing office in 2005 said that if the Osprey loses power while flying like a helicopter below 1,600 feet (490 m), emergency landings "are not likely to be survivable". But Captain Justin (Moon) McKinney, a V-22 pilot, says that this will not be a problem, "We can turn it into a plane and glide it down, just like a C-130".[31] A complete loss of power would require the failure of both engines, as a drive shaft connects the nacelles through the wing; one engine can power both proprotors.[36] While vortex ring state (VRS) contributed to a deadly V-22 accident, the aircraft is less susceptible to the condition than conventional helicopters and recovers more quickly.[5] The Marines now train new pilots in the recognition of and recovery from VRS and have instituted operational envelope limits and instrumentation to help pilots avoid VRS conditions.[32][37]

It was planned in 2000 to equip all V-22s with a nose-mounted Gatling gun, to provide "the V-22 with a strong defensive firepower capability to greatly increase the aircraft’s survivability in hostile actions."[30] The nose gun project was canceled however, leading to criticism by retired Marine Corps Commandant General James L. Jones, who is not satisfied with the current V-22 armament.[31] A belly-mounted turret was later installed on some of the first V-22s sent to the War in Afghanistan in 2009.[38]

With the first combat deployment of the MV-22 in October 2007, Time Magazine ran an article condemning the aircraft as unsafe, overpriced, and completely inadequate.[31] The Marine Corps, however, responded with the assertion that much of the article’s data were dated, obsolete, inaccurate, and reflected expectations that ran too high for any new field of aircraft.[39]

Recent development

On 28 September 2005, the Pentagon formally approved full-rate production for the V-22.[40] The plan is to boost production from 11 a year to between 24 and 48 a year by 2012. Of the 458 total planned, 360 are for the Marine Corps, 48 for the Navy, and 50 for the Air Force at an average cost of 0 million per aircraft, including development costs.[2] The V-22 had an incremental flyaway cost of million per aircraft in 2007,[3] but the Navy hopes to shave about million off that cost after a five-year production contract starts in 2008.[41]

The Bell-Boeing Joint Project Office in Amarillo, Texas will design a new integrated avionics processor to resolve electronics obsolescence issues and add new network capabilities.[42]


The Osprey is the world’s first production tiltrotor aircraft, with one three-bladed proprotor, turboprop engine, and transmission nacelle mounted on each wingtip. It is classified as a powered lift aircraft by the Federal Aviation Administration.[43] For takeoff and landing, it typically operates as a helicopter with the nacelles vertical (rotors horizontal). Once airborne, the nacelles rotate forward 90° in as little as 12 seconds for horizontal flight, converting the V-22 to a more fuel-efficient, higher-speed turboprop airplane. STOL rolling-takeoff and landing capability is achieved by having the nacelles tilted forward up to 45°. For compact storage and transport, the V-22’s wing rotates to align, front-to-back, with the fuselage. The proprotors can also fold in a sequence taking 90 seconds.[44]

Most Osprey missions will use fixed wing flight 75 percent or more of the time, reducing wear and tear on the aircraft and reducing operational costs.[45] This fixed wing flight is higher than typical helicopter missions allowing longer range line-of-sight communications and so improved command and control.[2] Boeing has stated the V-22 design loses 10% of its vertical lift over a Tiltwing design when operating in helicopter mode because of airflow resistance due to the wings, but that the Tiltrotor design has better short takeoff and landing performance.[46]

The V-22 is equipped with a glass cockpit, which incorporates four Multi-function displays (MFDs) and one shared Central Display Unit (CDU), allowing the pilots to display a variety of images including: digimaps centered or decentered on current position, FLIR imagery, primary flight instruments, navigation (TACAN, VOR, ILS, GPS, INS), and system status. The flight director panel of the Cockpit Management System (CMS) allows for fully-coupled (aka: autopilot) functions which will take the aircraft from forward flight into a 50-foot hover with no pilot interaction other than programming the system.[47] The glass cockpit of the canceled CH-46X was derived from the V-22.[48]

The V-22 is a fly-by-wire aircraft with triple-redundant flight control systems.[49] With the nacelles pointing straight up in conversion mode at 90° the flight computers command the aircraft to fly like a helicopter, with cyclic forces being applied to a conventional swashplate at the rotor hub. With the nacelles in airplane mode (0°) the flaperons, rudder, and elevator fly the aircraft like an airplane. This is a gradual transition and occurs over the rotation range of the nacelles. The lower the nacelles, the greater effect of the airplane-mode control surfaces.[50] The nacelles can rotate past vertical to 97.5° for rearward flight.[51][52]

The Osprey can be armed with one M240 7.62x51mm NATO (.308 in caliber) or M2 .50 in caliber (12.7 mm) machine gun on the loading ramp, that can be fired rearward when the ramp is lowered. A GAU-19 three-barrel .50 in gatling gun mounted below the V-22’s nose has also been studied for future upgrade.[31][53] BAE Systems developed a remotely operated turreted weapons system for the V-22,[54] which was installed on half of the first V-22s deployed to Afghanistan in 2009.[38] The 7.62 mm belly gun turret is remotely operated by a gunner inside the aircraft, who acquires targets with a separate pod using color television and forward looking infrared imagery.

U.S. Naval Air Systems Command is working on upgrades to increase the maximum speed from 250 knots (460 km/h; 290 mph) to 270 knots (500 km/h; 310 mph), increase helicopter mode altitude limit from 10,000 feet (3,000 m) to 12,000 feet (3,700 m) or 14,000 feet (4,300 m), and increase lift performance.[55]

Operational history

US Marine Corps

Marine Corps crew training on the Osprey has been conducted by VMMT-204 since March 2000. On 3 June 2005, the Marine Corps helicopter squadron Marine Medium Helicopter 263 (HMM-263), stood down to begin the process of transitioning to the MV-22 Osprey.[56] On 8 December 2005, Lieutenant General Amos, commander of the II MEF, accepted the delivery of the first fleet of MV-22s, delivered to HMM-263. The unit reactivated on 3 March 2006 as the first MV-22 squadron and was redesignated VMM-263. On 31 August 2006, VMM-162 (the former HMM-162) followed suit. On 23 March 2007, HMM-266 became Marine Medium Tiltrotor Squadron 266 (VMM-266) at Marine Corps Air Station New River, North Carolina.[57]

The Osprey has been replacing existing CH-46 Sea Knight squadrons.[58] The MV-22 reached initial operational capability (IOC) with the U.S. Marine Corps on 13 June 2007.[1] On 10 July 2007 an MV-22 Osprey landed aboard the Royal Navy aircraft carrier, HMS Illustrious in the Atlantic Ocean. This marked the first time a V-22 had landed on any non-U.S. vessel.[59]

On 13 April 2007, the U.S. Marine Corps announced that it would be sending ten V-22 aircraft to Iraq, the Osprey’s first combat deployment. Marine Corps Commandant, General James Conway, indicated that over 150 Marines would accompany the Osprey set for September deployment to Al-Asad Airfield.[60][61] On 17 September 2007, ten MV-22Bs of VMM-263 left for Iraq aboard the USS Wasp. The decision to use a ship rather than use the Osprey’s self-deployment capability was made because of concerns over icing during the North Atlantic portion of the trip, lack of available KC-130s for mid-air refueling, and the availability of the USS Wasp.[62]

The Osprey has provided support in Iraq, racking up some 2,000 flight hours over three months with a mission capable availability rate of 68.1% as of late-January 2008.[63] They are primarily used in Iraq’s western Anbar province for routine cargo and troop movements, and also for riskier "aero-scout" missions. General David Petraeus, the top U.S. military commander in Iraq, used one to fly around Iraq on Christmas Day 2007 to visit troops.[64] Then-presidential candidate Barack Obama also flew in Ospreys during his high profile 2008 tour of Iraq.[65]

The only major problem has been obtaining the necessary spare parts to maintain the aircraft.[66] The V-22 had flown 3,000 sorties totaling 5,200 hours in Iraq as of July 2008.[67] USMC leadership expect to deploy MV-22s to Afghanistan in 2009.[66][68] General George J. Trautman, III praised the increased range of the V-22 over the legacy helicopters in Iraq and said that "it turned his battle space from the size of Texas into the size of Rhode Island."[69]

Naval Air Systems Command has devised a temporary fix for sailors to place portable heat shields under Osprey engines to prevent damage to the decks of some of the Navy’s smaller amphibious ships, but they determined that a long term solution to the problem would require these decks be redesigned with heat resistant deck coatings, passive thermal barriers and changes in ship structure in order to operate V-22s and F-35Bs.[70]

A Government Accountability Office study reported that by January 2009 the Marines had 12 MV-22s operating in Iraq and they managed to successfully complete all assigned missions. The same report found that the V-22 deployments had mission capable rates averaging 57% to 68% and an overall full mission capable rate of only 6%. It also stated that the aircraft had shown weakness in situational awareness, maintenance, shipboard operations and the ability to transport troops and external cargo.[71] That study also concluded that the "deployments confirmed that the V-22’s enhanced speed and range enable personnel and internal cargo to be transported faster and farther than is possible with the legacy helicopters it is replacing".[71]

The MV-22 saw its first offensive combat mission, Operation Cobra’s Anger on 4 December 2009. Ospreys assisted in inserting 1,000 Marines and 150 Afghan troops into the Now Zad Valley of Helmand Province in southern Afghanistan to disrupt communication and supply lines of the Taliban.[38] In January 2010 the MV-22 Osprey is being sent to Haiti as part of Operation Unified Response relief efforts after the earthquake there. This will be the first use the Marine V-22 in a humanitarian mission.[72]

US Air Force

The Air Force’s first operational CV-22 Osprey was delivered to the 58th Special Operations Wing (58th SOW) at Kirtland Air Force Base, New Mexico on 20 March 2006. This and subsequent aircraft will become part of the 58th SOW’s fleet of aircraft used for training pilots and crew members for special operations use.[73] On 16 November 2006, the Air Force officially accepted the CV-22 in a ceremony conducted at Hurlburt Field, Florida.[74]

The US Air Force’s first operational deployment of the Osprey sent four CV-22s to Mali in November 2008 in support of Exercise Flintlock. The CV-22s flew nonstop from Hurlburt Field, Florida with in-flight refueling.[5] AFSOC declared that the 8th Special Operations Squadron reached Initial Operational Capability on 16 March 2009, with six of its planned nine CV-22s operational.[75]

In June 2009, CV-22s of the 8th Special Operations Squadron delivered 43,000 pounds (20,000 kg) of humanitarian supplies to remote villages in Honduras that were not accessible by conventional vehicles.[76] In November 2009, the 8th SO Squadron and its six CV-22s returned from a three-month deployment in Iraq.[77]

The first possible combat loss of an Osprey occurred on 9 April, 2010, as a CV-22 went down near Qalat, Zabul Province, Afghanistan, killing four.[78][79]

Potential operators

In 1999 the V-22 was studied for use in the United Kingdom’s Royal Navy,[80] it has been raised several times as a candidate for the role of Maritime Airborne Surveillance and Control (MASC).[81]

Israel had shown interest in the purchase of MV-22s, but no order was placed.[82][83] Flightglobal reported in late 2009 that Israel has decided to wait for the CH-53K instead.[84]

The V-22 Osprey is a candidate for the Norwegian All Weather Search and Rescue Helicopter (NAWSARH) that is planned to replace the Westland Sea King Mk.43B of the Royal Norwegian Air Force in 2015.[85] The other candidates for the NAWSARH contract of 10-12 helicopters are AgustaWestland AW101 Merlin, Eurocopter EC225, NHIndustries NH90 and Sikorsky S-92.[86]

Bell Boeing has made an unsolicited offer of the V-22 for US Army medical evacuation needs.[87] However the Joint Personnel Recovery Agency issued a report that said that a common helicopter design would be needed for both combat recovery and medical evacuation and that the V-22 would not be suitable for recovery missions because of the difficulty of hoist operations and lack of self-defense capabilities.[88]

The US Navy remains a potential user of the V-22, but its role and mission with the Navy remains unclear. The latest proposal is to replace the C-2 Greyhound with the V-22 in the fleet logistics role. The V-22 would have the advantage of being able to land on and support non-carriers with rapid delivery of supplies and people between the ships of a taskforce or to ships on patrol beyond helicopter range.[89] Loren B. Thompson of the Lexington Institute has suggested V-22s for use in combat search and rescue and Marine One VIP transport, which also need replacement aircraft.[90]


•• Pre-production full-scale development aircraft used for flight testing. These are unofficially considered A-variants after 1993 redesign.[91]

•• The U.S. Navy considered an HV-22 to provide combat search and rescue, delivery and retrieval of special warfare teams along with fleet logistic support transport. However, it chose the MH-60S for this role in 1992.[92]

•• The proposed anti-submarine warfare Navy variant. The Navy studied the SV-22 in the 1980s to replace S-3 and SH-2 aircraft.[93]

•• Basic U.S. Marine Corps transport; original requirement for 552 (now 360). The Marine Corps is the lead service in the development of the V-22 Osprey. The Marine Corps variant, the MV-22B, is an assault transport for troops, equipment and supplies, capable of operating from ships or from expeditionary airfields ashore. It is replacing the Marine Corps’ CH-46E[57] and CH-53D.[94]

•• Air Force variant for the U.S. Special Operations Command (USSOCOM). It will conduct long-range, special operations missions, and is equipped with extra fuel tanks and terrain-following radar.[95][96]

Notable accidents

Main article: Accidents and incidents involving the V-22 Osprey

From 1991 to 2000 there were four significant crashes, and a total of 30 fatalities, during testing.[32] Since becoming operational in 2007, the V-22 has had one possible combat loss due to an unknown cause, no losses due to accidents, and seven other notable, but minor, incidents.

• On 11 June 1991, a mis-wired flight control system led to two minor injuries when the left nacelle struck the ground while the aircraft was hovering 15 feet (4.6 m) in the air, causing it to bounce and catch fire.[97]

• On 20 July 1992, a leaking gearbox led to a fire in the right nacelle, causing the aircraft to drop into the Potomac River in front of an audience of Congressmen and other government officials at Quantico, killing all seven on board and grounding the aircraft for 11 months.[98]

• On 8 April 2000, a V-22 loaded with Marines to simulate a rescue, attempted to land at Marana Northwest Regional Airport in Arizona, stalled when its right rotor entered vortex ring state, rolled over, crashed, and exploded, killing all 19 on board.[37]

• On 11 December 2000, after a catastrophic hydraulic leak and subsequent software instrument failure, a V-22 fell 1,600 feet (490 m) into a forest in Jacksonville, North Carolina, killing all four aboard. This caused the Marine Corps to ground their fleet of eight V-22s, the second grounding that year.[99][100]

The Jaguar E-Type (UK) or XK-E (US) is a British automobile manufactured by Jaguar between 1961 and 1974. Its combination of good looks, high performance, and competitive pricing established the marque as an icon of 1960s motoring. A great success for Jaguar, over seventy thousand E-Types were sold during its lifespan.

In March 2008, the Jaguar E-Type ranked first in Daily Telegraph list of the "100 most beautiful cars" of all time.[2] In 2004, Sports Car International magazine placed the E-Type at number one on their list of Top Sports Cars of the 1960s.

The E-Type was initially designed and shown to the public as a grand tourer in two-seater coupé form (FHC or Fixed Head Coupé) and as convertible (OTS or Open Two Seater). The 2+2 version with a lengthened wheelbase was released several years later.

On its release Enzo Ferrari called it "The most beautiful car ever made".

The model was made in three distinct versions which are now generally referred to as "Series 1", "Series 2" and "Series 3". A transitional series between Series 1 and Series 2 is known unofficially as "Series 1½".

In addition, several limited-edition variants were produced:

• The "’Lightweight’ E-Type" which was apparently intended as a sort of follow-up to the D-Type. Jaguar planned to produce 18 units but ultimately only a dozen were reportedly built. Of those, one is known to have been destroyed and two others have been converted to coupé form. These are exceedingly rare and sought after by collectors.
• The "Low Drag Coupé" was a one-off technical exercise which was ultimately sold to a Jaguar racing driver. It is presently believed to be part of the private collection of the current Viscount Cowdray.

Concept versions

E1A (1957)

After their success at LeMans 24 hr through the 1950s Jaguars defunct racing department were given the brief to use D-Type style construction to build a road going sports car, replacing the XK150.

It is suspected that the first prototype (E1A) was given the code based on: (E): The proposed production name E-Type (1): First Prototype (A): Aluminium construction (Production models used steel bodies)

The car featured a monocoque design, Jaguar’s fully independent rear suspension and the well proved "XK" engine.

The car was used solely for factory testings and was never formally released to the public. The car was eventually scrapped by the factory

E2A (1960)

Jaguar’s second E-Type concept was E2A which unlike E1A was constructed from a steel chassis and used a aluminium body. This car was completed as a race car as it was thought by Jaguar at the time it would provide a better testing ground.

E2A used a 3 litre version of the XK engine with a Lucas fuel injection system.

After retiring from the LeMans 24 hr the car was shipped to America to be used for racing by Jaguar privateer Briggs Cunningham.

In 1961 the car returned to Jaguar in England to be used as a testing mule.

Ownership of E2A passed to Roger Woodley (Jaguars customer competition car manager) who took possession on the basis the car not be used for racing. E2A had been scheduled to be scrapped.

Roger’s wife Penny Griffiths owned E2A until 2008 when it was offered for sale at Bonham’s Quail Auction. Sale price was US.5 million

The Series 1 was introduced, initially for export only, in March 1961. The domestic market launch came four months later in July 1961.[7] The cars at this time used the triple SU carburetted 3.8 litre 6-cylinder Jaguar XK6 engine from the XK150S. The first 500 cars built had flat floors and external hood (bonnet) latches. These cars are rare and more valuable. After that, the floors were dished to provide more leg room and the twin hood latches moved to inside the car. The 3.8 litre engine was increased to 4.2 litres in October 1964.[7]

All E-Types featured independent coil spring rear suspension with torsion bar front ends, and four wheel disc brakes, in-board at the rear, all were power-assisted. Jaguar was one of the first auto manufacturers to equip cars with disc brakes as standard from the XK150 in 1958. The Series 1 can be recognised by glass covered headlights (up to 1967), small "mouth" opening at the front, signal lights and tail-lights above bumpers and exhaust tips under the licence plate in the rear.

3.8 litre cars have leather-upholstered bucket seats, an aluminium-trimmed centre instrument panel and console (changed to vinyl and leather in 1963), and a Moss 4-speed gearbox that lacks synchromesh for 1st gear ("Moss box"). 4.2 litre cars have more comfortable seats, improved brakes and electrical systems, and an all-synchromesh 4-speed gearbox. 4.2 litre cars also have a badge on the boot proclaiming "Jaguar 4.2 Litre E-Type" (3.8 cars have a simple "Jaguar" badge). Optional extras included chrome spoked wheels and a detachable hard top for the OTS.

An original E-Type hard top is very rare, and finding one intact with all the chrome, not to mention original paint in decent condition, is rather difficult. For those who want a hardtop and aren’t fussy over whether or not it is an original from Jaguar, several third parties have recreated the hardtop to almost exact specifications. The cost ranges anywhere from double to triple the cost of a canvas/vinyl soft top.

A 2+2 version of the coupé was added in 1966. The 2+2 offered the option of an automatic transmission. The body is 9 in (229 mm) longer and the roof angles are different with a more vertical windscreen. The roadster remained a strict two-seater.

There was a transitional series of cars built in 1967-68, unofficially called "Series 1½", which are externally similar to Series 1 cars. Due to American pressure the new features were open headlights, different switches, and some de-tuning (with a downgrade of twin Zenith-Stromberg carbs from the original triple SU carbs) for US models. Some Series 1½ cars also have twin cooling fans and adjustable seat backs. Series 2 features were gradually introduced into the Series 1, creating the unofficial Series 1½ cars, but always with the Series 1 body style.

Less widely known, there was also right at the end of Series 1 production and prior to the transitional "Series 1½" referred to above, a very small number of Series 1 cars produced with open headlights.[8] These are sometimes referred to as "Series 1¼" cars.[9] Production dates on these machines vary but in right hand drive form production has been verified as late as March 1968.[10] It is thought that the low number of these cars produced relative to the other Series make them amongst the rarest of all production E Types.

An open 3.8 litre car, actually the first such production car to be completed, was tested by the British magazine The Motor in 1961 and had a top speed of 149.1 mph (240.0 km/h) and could accelerate from 0-60 mph (97 km/h) in 7.1 seconds. A fuel consumption of 21.3 miles per imperial gallon (13.3 L/100 km; 17.7 mpg-US) was recorded. The test car cost £2097 including taxes.[11]

Open headlights without glass covers, a wrap-around rear bumper, re-positioned and larger front indicators and taillights below the bumpers, better cooling aided by an enlarged "mouth" and twin electric fans, and uprated brakes are hallmarks of Series 2 cars. De-tuned in US, but still with triple SUs in the UK, the engine is easily identified visually by the change from smooth polished cam covers to a more industrial ‘ribbed’ appearance. Late Series 1½ cars also had ribbed cam covers. The interior and dashboard were also redesigned, with rocker switches that met U.S health and safety regulations being substituted for toggle switches. The dashboard switches also lost their symmetrical layout. New seats were fitted, which purists claim lacked the style of the originals but were certainly more comfortable. Air conditioning and power steering were available as factory options.

Production according to Graham[12] is 13,490 of all types.

A new 5.3 L 12-cylinder Jaguar V12 engine was introduced, with uprated brakes and standard power steering. The short wheelbase FHC body style was discontinued and the V12 was available only as a convertible and 2+2 coupé. The convertible used the longer-wheelbase 2+2 floorplan. It is easily identifiable by the large cross-slatted front grille, flared wheel arches and a badge on the rear that proclaims it to be a V12. There were also a very limited number of 4.2 litre six-cylinder Series 3 E-Types built. These were featured in the initial sales literature. It is believed these are the rarest of all E-Types of any remaining.

In 2008 a British classic car enthusiast assembled what is surely the last ever E-Type from parts bought from the end-of-production surplus in 1974.[15]

Graham[12] lists production at 15,290.

Limited edtions

Two limited production E-Type variants were made as test beds, the Low Drag Coupe and Lightweight E-Type, both of which were raced:

Low Drag Coupé (1962)

Shortly after the introduction of the E-Type, Jaguar management wanted to investigate the possibility of building a car more in the spirit of the D-Type racer from which elements of the E-Type’s styling and design were derived. One car was built to test the concept designed as a coupé as its monocoque design could only be made rigid enough for racing by using the "stressed skin" principle. Previous Jaguar racers were built as open-top cars because they were based on ladder frame designs with independent chassis and bodies. Unlike the steel production E-Types the LDC used lightweight aluminium. Sayer retained the original tub with lighter outer panels riveted and glued to it. The front steel sub frame remained intact, the windshield was given a more pronounced slope and the rear hatch welded shut. Rear brake cooling ducts appeared next to the rear windows,and the interior trim was discarded, with only insulation around the transmission tunnel. With the exception of the windscreen, all cockpit glass was plexi. A tuned version of Jaguar’s 3.8 litre engine with a wide angle cylinder-head design tested on the D-Type racers was used. Air management became a major problem and, although much sexier looking and certainly faster than a production E-Type, the car was never competitive: the faster it went, the more it wanted to do what its design dictated: take off.

The one and only test bed car was completed in summer of 1962 but was sold a year later to Jaguar racing driver Dick Protheroe who raced it extensively and eventually sold it. Since then it has passed through the hands of several collectors on both sides of the Atlantic and now is believed to reside in the private collection of the current Viscount Cowdray.

Lightweight E-Type (1963-1964)

In some ways, this was an evolution of the Low Drag Coupé. It made extensive use of aluminium alloy in the body panels and other components. However, with at least one exception, it remained an open-top car in the spirit of the D-Type to which this car is a more direct successor than the production E-Type which is more of a GT than a sports car. The cars used a tuned version of the production 3.8 litre Jaguar engine with 300 bhp (224 kW) output rather than the 265 bhp (198 kW) produced by the "ordinary" version. At least one car is known to have been fitted with fuel-injection.

The cars were entered in various races but, unlike the C-Type and D-Type racing cars, they did not win at Le Mans or Sebring.

Motor Sport

Bob Jane won the 1963 Australian GT Championship at the wheel of an E-Type.

The Jaguar E-Type was very successful in SCCA Production sports car racing with Group44 and Bob Tullius taking the B-Production championship with a Series-3 V12 racer in 1975. A few years later, Gran-Turismo Jaguar from Cleveland Ohio campaigned a 4.2 L 6 cylinder FHC racer in SCCA production series and in 1980, won the National Championship in the SCCA C-Production Class defeating a fully funded factory Nissan Z-car team with Paul Newman.
