Grumman
Coniar Turbo Firecat

The Conair Firecat is a fire-fighting aircraft developed in Canada in the 1970s by modifying military surplus Grumman S-2 Trackers. The modifications were developed by the maintenance arm of the Conair Group, which became a separate company called Cascade Aerospace.

The Firecats are retrofitted Grumman S-2 Trackers. Conair bought a large number of Trackers formerly operated by the Canadian Navy and a small number of ex-United States Navy aircraft as well. The Trackers are modified for aerial firefighting as Firecats by raising the cabin floor by 20 cm (8 in) and fitting a 3,296-litre (870 U.S. gal) retardant tank where the torpedo bay is normally located. All superfluous military equipment is removed and the empty weight is almost 1,500 kg lower than a Tracker's The first aircraft was modified in 1978. Some examples have been re-engined with turboprop engines and are known as Turbo Firecats, these feature a larger tank and extra underwing fuel tanks; the Maximum Take Off Weight (MTOW) is increased by 680 kg (1,500 lb) to 12,480 kg (27,500 lb), while the lighter turbine engines also reduce the empty weight. The first Turbo Firecat was produced in 1988
