Percival Provost
The RAF’s Last Piston Trainer

The radial-engined basic trainer that taught a decade of RAF pilots with fighter-like handling, fathered the Jet Provost, and went to war as a light-attack aircraft in Oman, Rhodesia and Burma.

The Story

The Provost: how a Luton trainer bridged the RAF from Tiger Moth thinking to the jet age

In September 1948 the Air Ministry issued Specification T.16/48 for a new basic trainer to replace the Percival Prentice. The Prentice was docile but underpowered and dull, and the RAF wanted an aircraft that would sort out unsuitable students early, with an instructor sitting close enough to watch every move. More than thirty proposals arrived. Two were chosen for prototypes: the Handley Page H.P.R.2 and Percival’s P.56, drawn by the Polish-born engineer Henry Millicer. The first P.56, WE522, flew on 24 February 1950 with an Armstrong Siddeley Cheetah radial. After a fly-off at Boscombe Down and tropical trials abroad, the Ministry picked the Percival design, fitted with the much more powerful nine-cylinder Alvis Leonides, and in May 1951 ordered 200. It was named Provost.

The Provost was a straightforward, all-metal, low-wing monoplane with a fixed tailwheel undercarriage and side-by-side seats under a three-piece canopy. What made it special was the engine: about 550 hp, roughly twice the power of the Prentice, in an aircraft of under two tonnes. Pilots found a rapid climb, light, well-harmonised controls and a roll rate commonly quoted at more than 90 degrees a second, close to the best fighters of the day. Deliveries began at the Central Flying School in 1953, No. 6 Flying Training School at Ternhill started re-equipping on 1 July, and the first students began training that October. By September 1954 the Provost had replaced the Prentice entirely.

For the rest of the 1950s every RAF pilot trainee went solo on a Provost before moving on to the Vampire T.11. The RAF took 397 of the 461 built. Then the Air Ministry asked a radical question: why not teach from the start on a jet? Hunting Percival answered with a jet-powered derivative, the Jet Provost, which steadily took over from 1959 onwards. The piston Provost lingered in second-line roles until November 1969. Abroad its career ran longer and harder. Armed T.52 and T.53 versions went to Rhodesia, Oman, Burma, Iraq, Sudan and Ireland, and in the jungles of Burma, the mountains of Dhofar and the Rhodesian bush, the trainer flew real combat sorties.

01The Provost at war: a trainer with guns in three insurgencies

Percival built armed export versions from the start. The T.52 and T.53 carried two machine guns and up to about 500 lb of bombs or rockets, which turned a basic trainer into a cheap counter-insurgency aircraft for air forces with little else. Burma was the biggest customer, eventually acquiring about 40. Based at Meiktila but operating mostly from small jungle strips, Burmese Provosts flew numerous sorties against communist and ethnic insurgents in the early 1960s, though inexperienced crews, poor co-ordination with ground troops and the near-impossibility of finding targets under the canopy limited their effect.

In Oman, the Sultan’s Air Force was formed on 1 March 1959 with a few ex-RAF Provost T.52s. When the Dhofar rebellion broke out in 1962, the service took on twelve armed Provosts, which saw extensive close air support use until faster BAC Strikemasters began arriving in 1968. In Rhodesia, the air force had twelve Provosts at the unilateral declaration of independence in 1965. Under sanctions, engineers replaced the type’s cartridge starter with a truck starter motor, and Provosts were among the aircraft that carried the home-made Frantan fire bombs during the bush war. By the end of the war they served alongside SIAI-Marchetti SF.260s with No. 6 Squadron.

Design & Engineering

What makes the Provost special

The Leonides radial

The Alvis Leonides was a compact nine-cylinder air-cooled radial of about 550 hp, driving a three-bladed constant-speed propeller. In the Provost it produced a climb to 10,000 ft in a little over three minutes, remarkable for a basic trainer of 1950. It also meant students had to learn to manage a powerful, high-torque engine and a variable-pitch propeller from the very beginning of their training, much as they would on a fighter.

Side by side, under watch

The specification demanded closer supervision of students, and the Provost seated instructor and pupil side by side. The instructor could see the student’s hands, eyes and instruments at a glance, catching problems that a tandem layout would hide. The controls were grouped logically on a central console. The same thinking carried into the Jet Provost and, later, other side-by-side trainers such as the Strikemaster.

Amber screens for blind flying

To teach instrument flying, the Provost’s three-piece canopy could be fitted with extendible amber screens. The student wore blue-tinted goggles, so the amber panels appeared opaque and he had to fly on instruments alone, while the instructor, without goggles, could still see outside normally. It was a simple and effective solution, and the aircraft also had VHF radio for ground-controlled approach practice.

02The Provost’s variants: from RAF T.1 to armed exports

Prototypes: WE522 and WE530 with Armstrong Siddeley Cheetah radials, later re-engined, plus a Leonides-powered third aircraft.
Provost T.1: RAF basic trainer with the Alvis Leonides; 397 delivered to the RAF.
T.51: unarmed export trainer, for Ireland, early Rhodesian deliveries and Malaysia.
T.52: armed export version with two machine guns and underwing stores, for Rhodesia and Oman.
T.53: armed export version for Burma, Iraq, Ireland and Sudan.
Jet Provost: a jet derivative developed from the Provost with an Armstrong Siddeley Viper turbojet and nosewheel undercarriage, the RAF’s next basic trainer.

Costs & production

Unit cost: No reliable contract price has been published

03The Provost’s export customers: who flew it

Rhodesia: four T.51 ordered in 1953, twelve armed T.52 delivered in 1955, more acquired in 1968 despite the arms embargo.
Ireland: four T.51 ordered in January 1954 and six armed T.53 in 1960.
Burma: first order for 12 T.53 in 1954; about 40 in all.
Iraq: 15 T.53, deliveries from 1955.
Sudan: four T.53 in 1957, two soon lost in accidents; three more in 1959 and five ex-RAF.
Oman: ex-RAF aircraft as armed T.52s from 1959.
Malaysia: 24 T.51 between 1961 and 1968.

04The Provost’s operating costs: what a Leonides costs to run

Official RAF hourly costs for the Provost have not been published. For civil owners today, the dominant costs are fuel for a 550 hp radial, oil, and above all the scarcity of Alvis Leonides parts and overhaul expertise, which has kept several survivors on the ground for years. Our range of about £700–1,200 per hour is an order-of-magnitude estimate for private warbird operation and should not be taken as a quoted price.

Training

Thirty designs, one winner

How the Provost beat the Handley Page H.P.R.2.

Read the full story

Specification T.16/48 attracted more than thirty proposals. The Air Ministry funded two, the Percival P.56 and the Handley Page H.P.R.2, which was built by Handley Page’s Reading works. Both were flown hard at Boscombe Down, and the Percival aircraft was also sent abroad for tropical trials. Test reports praised its handling and asked only for minor refinements. Fitted with the Leonides, the P.56 won, and the H.P.R.2 became a footnote.

People

Henry Millicer’s first trainer

The designer who later created the Airtourer.

Read the full story

The Provost was designed under Henry Millicer, a Polish-born engineer who had come to Britain and joined Percival. He later moved to Australia, where he designed the Victa Airtourer, an all-metal light aircraft that won a design competition and went on to be built in Australia and New Zealand. The Provost’s clean, uncomplicated structure and pleasant handling foreshadow his later work.

Training

Flying blind behind amber

A coloured-filter trick for instrument training.

Read the full story

The Provost’s instrument training used the two-stage amber system: amber panels fitted inside the canopy and blue goggles worn by the pupil. Together the two filters block almost all light, so the student saw nothing outside, while the instructor saw the world through what looked like tinted glass. It let instructors teach instrument flying in the real aircraft in good weather, with full lookout maintained.

Display

The Sparrows

The Central Flying School’s piston display team.

Read the full story

In 1957 the Central Flying School formed a display team called The Sparrows, flying piston-engined Provosts led by Flt Lt J. Kingsbury. The team later converted to the Jet Provost T.1 under Flt Lt N. Griffin, a small sign of the jet trainer that was about to take the Provost’s place. The CFS tradition of trainer display teams led eventually to the Red Pelicans and the Red Arrows.

Training

From Ternhill to Cranwell

A decade of RAF pilots went solo on the type.

Read the full story

No. 6 Flying Training School at Ternhill was the first to re-equip, from 1 July 1953, and the first student course started in October. Provosts went on to equip Nos. 2, 3 and 22 FTS, the RAF College at Cranwell, several University Air Squadrons, the Central Navigation and Control School and even the Empire Test Pilots’ School. The RAF Museum lists units at Ternhill, Syerston, Hullavington, Feltwell and Worksop.

Combat

Close air support in Dhofar

Oman’s first combat aircraft.

Read the full story

The Sultan of Muscat and Oman’s Air Force was formed on 1 March 1959 with three, later five, Provost T.52s transferred from the RAF. When the Dhofar rebellion began in 1962, it added twelve armed Provosts, which flew extensive close air support over the jebel. They carried the war until BAC Strikemasters started arriving in 1968. The Shuttleworth Collection’s XF603 recalls this era: it wears the camouflage applied for delivery to Oman, with RAF roundels for the ferry flight.

Combat

Fire bombs over the bush

Rhodesia keeps its Provosts flying under sanctions.

Read the full story

When Rhodesia declared independence in 1965 it had twelve Provosts. Cut off from British spares, its engineers improvised: the Provost’s cartridge starter was replaced by a truck starter motor. The aircraft carried the locally made Frantan napalm bombs, as did the Hunters and Lynxes, and by the end of the bush war they were flying with No. 6 Squadron alongside SF.260 Genets.

Combat

Jungle strips in Burma

Burma’s armed trainers in a counter-insurgency war.

Read the full story

Burma acquired about 40 Provosts, forming two units. Officially based at Meiktila, they mainly flew from small jungle runways in the early 1960s, attacking communist, Karen and other ethnic rebel forces. Accounts of the campaign are frank about the limits: pilots were inexperienced, targets hard to identify under the forest canopy and co-operation with ground troops poor.

Accident

Sudan’s hard start

Half the first batch lost within months.

Read the full story

Sudan ordered four armed T.53 Provosts in May 1957, and two were lost in accidents shortly after delivery. The air force persisted, buying three more in 1959 and five former RAF aircraft later, and the Provost became one of the foundation types of the young Sudanese air arm.

XF597 was built at Luton on 31 January 1955 and served with maintenance units, the RAF College at Cranwell and the College of Air Warfare at Manby before retiring in 1964. Sold to Flint Technical College as an instructional airframe, it was registered G-BKFW in 1982 and restored to fly by Alan House in 1988. Since July 2018 it has been in the care of the group Provost Preservation, which is working to keep it airworthy.

Read the full story

The RAF Museum displays Provost T.1 WV562 in Hangar 1 at its Midlands site at Cosford. The museum describes the Provost as the last piston-engined basic trainer used by the RAF and notes its good aerobatic qualities, which made it popular with instructors and students during a service life of around 16 years.
