One proposed Sea Vixen design carries a 4.5-inch recoilless gun for anti-shipping work. Its hypothetical use against a large bomber such as the Tu-95 also prompts speculation about the damage a hit would cause. Such a weapon would challenge a broad claim associated with A-10 publicity about the largest gun fitted to an aircraft. German cannon-armed aircraft, Spectre gunships and an Italian bomber project supply competing examples. The Mosquito provides a further comparison for using aircraft guns against submarines, although several aircraft names and gun details remain uncertain in this passage.
