Hawker Siddeley HS-1127 Harrier

The Harrier family was started with the Hawker P.1127. Design began in 1957 by Sir Sidney Camm, Ralph Hooper of Hawker Aviation and Stanley Hooker of the Bristol Engine Company. Rather than using rotors or a direct jet thrust the P.1127 had an innovative vectored thrust turbofan engine and the first vertical take-off was on October 21, 1960. Six prototypes were built in total, one of which was lost at an air display.

Hawker Siddeley Kestrel

The P.1127 was renamed Kestrel after Hawker Siddeley Aviation was created. The Kestrel was an evaluation aircraft, and nine were produced, the first flying on March 7, 1964. The Kestrel had fully swept wings and a larger tail than the P.1127, and the fuselage was modified to take the larger 15,000 lbf (85 kN) Pegasus engine. Due to interest from the US and Germany the Tri-partite Evaluation Squadron was formed, staffed by military test pilots from Britain, the US and West Germany. After testing at RAF West Raynham, the eight surviving evaluation aircraft were transferred to the USA for evaluation by the Army, Air Force and Navy (including USMC) as the XV-6A. After Tri-Service evaluation they were passed to the USAF for further evaluation at Edwards AFB.

An order for 60 aircraft was received from the RAF in 1966, and the first pre-production Harriers were flying by mid-1967.

Harrier GR.1

The Harrier GR Mk.1 was the first production model taken from the Kestrel, it first flew on December 28, 1967, and entered service with the RAF on April 1, 1969. Construction took place at factories in Kingston-upon-Thames in southwest London and at Dunsfold, Surrey. The latter adjoined an airfield used for flight testing; both factories have since closed. The ski-jump technique for STOL use by Harriers launched from Royal Navy aircraft carriers was tested at the Royal Navy's airfield at Yeovilton, Somerset. Their flight decks were designed with an upward curve to the bow following the successful conclusion of those tests. The air combat technique of vectoring in forward flight, or viffing, was evolved in the Harrier to outmaneuver a hostile aircraft or other inbound weapon.

Harrier GR.1A

The GR.Mk 1A was an upgraded version of the GR.Mk 1, the main difference being the uprated Pegasus Mk 102. 58 GR.Mk 1As entered RAF service, 17 GR.Mk 1As were produced and a further 41 GR.Mk 1s were upgraded.

Harrier GR.Mk 3

The Harrier GR.3 featured improved sensors, countermeasures and a further uprated Pegasus Mk 103 and was to be the ultimate development of the 1st generation Harrier. They bravely fought in the Falklands War.

Flew the AV-8 for 15 years with the US Marines and Italian Navy! Most exciting aircraft in the world!!

viggen can back on the ground. but a harrier it can back into the air.
Harrier makes things like f-35b can not do. guess what?.

The Harrier exemplifies the RAF motto of "Agile - Adaptable - Capable." The Harriers accounted for 28% of Argentinian combat air losses while losing none in air-to-air combat during the Falkland Islands War. All of this, and more, is covered in chapter 5 of my new book. Here is the info.:

The U.S. Marines used Harriers, but the U.S. Navy rejected them. Why the U.S. Navy should have done that is still baffling. The only reason I can uncover was a prejudice against the operation of single-engine carrier-based aircraft, which makes as little sense as the prejudice the British once had against monoplanes.

I have since read that the U.S. Navy is planning to reject the new F-35 VTOL fighter because it lacks an effective tail hook. What does a VTOL aircraft need with a tail hook? Madness!

Capt. Robert Thomas, 30.08.2011

Sea Harrier coupled with the USN concept Sea Control Ship c.1970 could have made all navies (and aircraft carries) obsolete. At one fifth the cost of a CVA, a vast fleet was possible and freedom of the seas assured.

hey

David Horton, 28.02.2011

Anyone know the whereabouts of Robin Kent? - old bucaneer pilot - flew AV-8A's with the US Marines then back to the Sea Harrier. He was my squadron mate in VMA-231 -

Andreas F., 09.02.2011

The picture on top and the 3-view-drawing show a H.S.1174 (two seat) and not a P.1127 (single seat) Kestrel/Harrier.

Denis thaddeus, 01.02.2011

A HS 1127 once landed at my school, st Fransis in Crawley, about 65.

Ian, 05.07.2010

The hallmark of an excellent combat aircraft: The Americans will use it too as they never use anything built by "Other People". Harrier, Canberra, Hawk & Spitfire. All classics.

Barry Smith, 11.06.2010

It was mentioned that the Canberra was the only modern British aircraft to be licence built in the USA. Surely, they built this too? Did they not have a licence ?

John Beard, 21.12.2009

Just for further information The Squadron though based at West Rainham did most of its testing off site at Military Ranges and closed RAF Stations namely Bircham Newton, North Pickering & Stamford Range. I was attached to the Squdron for a While

Shame about the P1154 (Not featured here). Would've been a world-beater - a supersonic Harrier. Typical British government. Would rather its councils fund cake shops for lesbians!

chaiwat kosatanakom, 12.08.2009

In Thailand, kids enjoys making the Harrier from paper model which enable them to learn how to make understand the VSTOL. It's amazing for them. Today, aircraft paper model is very popular among children nationwide due to its economy cost and being recyclebale. It's absolutely enlighten them to learn the aviation.

lewis, 15.07.2009

the sea harrier should never have been taken out of service!

chuck massey, 12.07.2009

also there were other pilots maj paul curry us army maj john a johnston us army cdr j j tyson usnavy

Cody302, 26.05.2009

I thought Harriers were all Sub-Sonic,but the text above indicates one and a quarter mach??

Renee, 23.01.2007

Do you know the names of the pilots that made up the Tripartite Kestrel Evaluation squadron I think the German was the famous Barkhorn??? I would love to know their names.
Thanks

Do you have any comments about this aircraft ?
