The Vickers Type 143 or Bolivian Scout was a British single seat fighter biplane designed and built by Vickers in 1929-1930. Six were built for Bolivia in 1930, which used the survivors in the Chaco War against Paraguay.

Design and development

Early in 1929, Bolivia, which was engaged in border disputes with Paraguay over the Gran Chaco region, and was trying to build up its air forceAndrews and Morgan 1988, p. 235.] , placed an order with Vickers for six fighter aircraft, the Vickers Type 143. The Type 143, or Bolivian Scout , was a development of the earlier Vickers Type 141 fighter, with the Type 141's Rolls-Royce Kestrel engine replaced by a Bristol Jupiter VIA, already powering other aircraft used by the Bolivian Air Force, and a stronger undercarriage to cope with the rough airfield surfaces in Bolivia . It was an all-metal, single seat, biplane aircraft, with single bay wings.

The Type 143 first flew on 11 June 1929, and successfully met all performance criteria Mason 1992, p. 223.] . One of the six aircraft was evaluated by the Aeroplane and Armament Experimental Establishment (A & AEE) at Martlesham Heath before delivery to Bolivia.

A seventh aircraft, the Vickers Type 177 was built as a private venture to meet the requirements of Air Ministry Specification N.21/26 for a naval fighter, being fitted with a Jupiter XF engine and steerable wheel braking to aid on-deck manoeuvering. The Type 177 first flew on 26 November 1929 Andrews and Morgan 1988, p. 237. ] , and while it was shown to have a maximum speed of 190 mph (306 km/h) Mason 1992, p. 225] , with the Hawker Nimrod, not designed against this specification, chosen instead to meet the Fleet Air Arm's requirement for a fighter.

Operational history

Delivery of the six Type 143s to Bolivia began in January 1930 Green and Swanborough 1994 ] . While the type proved popular in Bolivian service Mason 1992, three of the six had been written off by the time that the border disputes between Bolivia and Paraguay escalated into the Chaco War. The three remaining Type 143s continued to serve in the Chaco War until superseded by Curtiss Hawks , damaging at least one Paraguayan Wibault 73 in air-to-air combatGreen and Swanborough 1994, p. 580.] .
