PROGRAMME: HS P1182 Hawk first flew 21 August 1974; first generation Hawk remains available and is marketed with advanced 100 Series and single-seat 200 Series (detailed separately) to meet customers' requirements; Hawk design leadership transferred from Kingston to Brough 1988, and final assembly and flight test from Dunsfold to Warton 1989. Brough subsequently assumed responsibility for final assembly, although first flights still at Warton.
Hawk 50 Series main exports made December 1980 to October 1985; largely supplanted by 60 Series; Hawk 100 enhanced ground attack export model announced mid-1982; first flight of 100 Series aerodynamic prototype (G-HAWK/ZA101 converted as Mk 100 demonstrator) 21 October 1987; trials of wingtip Sidewinder rails started at Warton in April 1990. Warton assembly line officially opened 24 October 1991.
