The jet was one of eleven Hunter F.4s converted to T.8C status for the Royal Navy in 1963.
It went into Fleet Air Arm service with RN 759 Sqn at RNAS Brawdy, where it served as aircraft '805/BY'.
In late 1969 XF994 moved to RNAS Yeovilton where it was used by the Naval Flying Standards Flight/Station Flight as '718/VL' for a few years until the jet went into store at Kemble. 

It remained at Kemble until October 1980 when after refurbishment it flew to Yeovilton and became a part of the FRADU.
XF994 kept its '718' identity for a short time until it was given the new call-sign '874' in early 1981.
During 1987/8 it underwent a re-spray to battleship grey and a change of identity, becoming '873/VL', and it remained in service until retirement in 1995. XF994 had the distinction of carrying out the last contracted task by a Navy Hunter on 17th February 1995, and it also took part in the 'goodbye Hunters' flypast in May the same year. It was subsequently flown to Shawbury and placed in storage.

During 1998 the aircraft was taken by road to Boscombe Down for restoration to flying condition.
However the plan did not go ahead and after a period of ground instructional use with the Apprentices School XF994 was towed to the Boscombe Down Museum facility and became an exhibit in 2001, where it remains today.

It was delivered to the Fleet Air Arm and went into service at RNAS Brawdy with RN 759 Sqn.
It's stay with the Squadron was brief as it was transferred to RN 764 Sqn in 1965, where it assumed the identity '688/LM'.
It remained in service until the Squadron disbanded in 1972 and it was placed in store.

During 1973/4 XF991 was moved to Yeovilton and became a part of the FRADU fleet of Hunters.
It was given a re-spray and given the identity '874/VL' and it flew numerous sorties with the Unit.
However in 1978 the aircraft's engine exploded during a flight, but the pilot successfully ejected.

The Royal Navy then acquired the airframe in 1985 and it was moved to RNAS Yeovilton for use with the FRADU.
It was re-sprayed into an all-grey colour scheme and subsequently had a career spanning some 8 years with the Unit, originally as aircraft '879' but later '874'. It was retired to RNAS Culdrose for ground training in March 1993, where it remained in use until 1996 when the was retired. It was placed up for disposal via auction in 1997. 

The aircraft was sold to Lynn Florey, an American pilot based in Belgium.
It was moved by road to Classic Jets' facilities at Exeter by road in September 1997 and was stored there until January 1999 when it left bound for Belgium. It was undergoing a restoration to bring it back to flying condition, but work has been suspended.

WT772 was converted to a T.8 by Armstrong Whitworth Aircraft Limited, Coventry in 1959 and it initially went to RN 764 Sqn at Lossiemouth. It was later assigned to No. 759 Sqn based at RNAS Brawdy, wearing the squadron codes '808/BY'.
In 1970 it moved to RNAS Yeovilton and became a part of the Air Direction Training Unit (ADTU) fleet originally as aircraft '736', but it later took on the identity '745'. In 1974 the aircraft was repainted and given the FRADU call-sign '875' and 'VL' shore code. 

On 21st September 1976 WT772 had an engine failure on take off, the pilot ejected successfully and escaped unharmed.
The empty aircraft landed in fields between the villages of Queen Camel and Charlton Adam on its belly and remained complete despite going through a number of hedges. The aircraft was recovered and moved back to Yeovilton and declared a write-off.
A replacement Hunter was brought onto FRADU's strength and WT772 passed to the station fire section, where it expired in 1980.

Converted to a T.8 for the Fleet Air Arm, XF289 went into service with RN 764 Sqn at RNAS Lossiemouth and was given the identity '709' with a 'LM' tail code. It's history between 1960 and 1972 is uncertain at the time of writing, but it's possible that XF289 remained with 764 Sqn until it's next posting to RNAS Yeovilton. In August 1970 the aircraft was noted serving with the Air Direction Training School and during 1972 it was a part of Yeovilton's station flight, coded '738/VL'. 

It seemingly joined the FRADU in 1974 where it was originally coded '872'.
By 1982 it had taken on the identity of '875' and it kept this throughout the remainder of its FRADU career, which ended in 1994 without any major incidents. It was offered for sale via auction, and George Lazik, based in the USA.
The aircraft were delivered to Exeter where they were prepared for the trip across the pond. On July 10, 1995 XF289, along with GA11 XE707 participated in an historic first ever crossing of the Atlantic Ocean by Hunters.
Former FRADU chief pilot Brian Grant and George shared the piloting responsibilities throughout the trip.
After arriving in the USA both aircraft went on to star on the air show circuit and to participate in the USAF Test Pilot School’s training curriculum.

It's current location is unknown - (CAN YOU HELP WITH INFORMATION??!!)
