Barracuda

The Barracuda is the Tau Empire's air superiority fighter, roughly equivalent to the Imperial Navy's Lightning Fighter. In the lore, the Barracuda is supposed to be slower than the Lightning and Thunderbolt, while being more maneuverable (than the latter, at least). However, in the rules, all three are exactly as fast as each other and the Lightning and the Barracuda are equally agile and armored. The Imperial and Tau vehicles do differ in one major respect: Imperial flyers have armored cockpits, while Tau cockpits also function as escape pods. Truly, the cowardice basic rationality and actual fucking concern for soldiers' lives of the alien knows no bounds.

The Barracuda's primary air-to-air weapon is a heavy ion cannon as long as the fuselage. This is supported by a pair of auto-targeting burst cannons in the wingtips, and supplemented with missile pods in the wings for ground attack. It can also take up to four seeker missiles to lend additional anti-armor support to markerlight-equipped ground forces. Once it eliminates all flying targets, Barracuda can start bombarding ground-pounders with overcharged ion cannon blasts and hails of missile and pulse fire, vaporizing everything that isn't AV13-14 or Sv2+. Tau usually avoid using it as a dedicated strafing runner though because of it's limited survivability compared to their regular bombers like Tiger Shark or Sun Shark.

Barracudas also serve as interceptors of the Tau space fleet, and have been proven quite capable of going toe-to-hoof with the likes of Fury. The fact that Mantas rarely need interceptor escort to fight off enemy interceptors means Tau may focus their Barracuda wings on defense against enemy ordinance, and if you know anything about Battlefleet Gothic, the one who wins the ordinance game while fleets are closing usually wins a battle.
