The Boulton Paul Defiant is stronger than River-n-White's usual AV-8. Its shots are automatically targeted towards an enemy. However, this can be a distraction to a player very used to positioning an ordinary plane in order to strike the enemy; in addition, there is no way to change the enemy at which the shots are aiming, meaning that the plane will not always strike where the player desires.
The Boulton's special weapon consists of four support wingmen who appear to either side of the plane. The wingmen automatically fire weapons and are invulnerable for a short period of time. After the invulnerability wears off, they will remain until struck with enemy fire.
