Scottish Aviation
Beagle Bulldog

A successful military trainer developed from the civilian Beagle Pup.
Scottish Aviation Bulldog G-AXIG G-AXIG was the first Bulldog completed by Scottish Aviation at Prestwick. It is seen here flying in Swedish Air Force colours.
The B.125 Bulldog was developed by Beagle Aircraft at Shoreham as a more powerful military trainer version of the Beagle B.121 Pup.
It is fully aerobatic and features an enlarged, fully-transparent sliding canopy and an increased wingspan when compared with the Beagle Pup.
It is fitted with a 200 hp Lycoming engine  driving a two-blade variable pitch propeller.
The first prototype Bulldog (G-AXEH) flew at Beagle's south-coast factory on 19th May 1969.
Unfortunately, later that same year saw the failure of Beagle Aircraft Limited following the withdrawal of government financial support and despite a full order book.
Responsibility for the type was transferred to Scottish Aviation whose first example (G-AXIG) flew on 14th February 1971, this aircraft having been initially registered by Beagle as their second B.125.

Both aircraft (G-AXEH and G-AXIG) were used by Scottish Aviation as demonstrators with one (G-AXIG) painted in Swedish Air force colours as ‘005’. This aircraft, which was originally flown on 14th February 1971, was subsequently sold on the civil market and for a number of years operated out of Compton Abbas Airfield in Wiltshire.
The S.A. Bulldog was also reasonably successful in the export market with sales of 78 aircraft to the Swedish Air Force, as well as several mainly African nations.  In the UK, the RAF purchased 130 aircraft for use as the Bulldog T Mk 1 Basic Trainer.
Scottish Aviation Bulldog 120 G-BHZP Botswana G-BHZP OD-3 was the single Scottish Aviation Bulldog delivered to the Botswana Defence Force.
The Swedish order was initially received by Beagle Aircraft although it was subsequently fulfilled by Scottish Aviation Limited who thereafter continued production at Prestwick, under the banner of newly-formed British Aerospace.
Scottish Aviation Bulldog 128 HKG-5 G-BULL G-BULL is a Bulldog 128 operating in the colours of the Royal Hong Kong Auxiliary Air Force.
One aircraft (G-BDOG) was fitted with a retractable undercarriage and displayed at Farnborough Air Show in 1976, bearing the type name ‘Bullfinch’. This version did not actually enter production however and is currently registered as a Bulldog 200.
In addition to Sweden, export customers also included Botswana, Ghana, Hong Kong, Jordan, Kenya, Lebanon, Malaysia, and Nigeria.
Scottish Aviation Bullfinch G-BDOG Cranfield G-BDOG is the sole retractable undercarriage Scottish Aviation Bullfinch, or Bulldog 200, seen taking off from Cranfield.
Following the withrawal of the type from its RAF Basic Training, University Air Squadron and Air Experience roles in 2001, 'civilianised' Bulldogs became popular in private and flying club ownership as the type offers good aerobatic performance, excellent handling qualities and good all-round view from the cockpit.
Scottish Aviation Bulldog 125 G-DISA G-DISA is an ex-Jordanian Bulldog modified for the instruction of pilots with disabilities.
In October 2018, some 55 examples appeared on the British Civil Aircraft Register, several of which are operated in their original RAF or export colour schemes.
Scottish Aviation Bulldog Old Warden Oct 18 XX513 G-KKKK XX513, the first RAF Bulldog, is now registered G-KKKK and seen here at Old Warden in October 2018.
