The B-41 Scythe is a Mach 2-capable variable-geometry strategic bomber developed by South Axiom. It was developed for low-level penetration of enemy air defenses (as a tactical/strategic bomber). The Scythe can deploy a range of bombs and nuclear and non-nuclear standoff munitions. The Scythe's design is heavily influenced by the US B-1 Lancer, the Russian Tu-22M Backfire and the Russian Tu-160 Blackjack.

The Scythe deploys its payload through an internal weapons bay, which can accommodate missiles, bombs or additional fuel. If a larger payload or extended range is required, external hardpoints are installed for more munitions or conformal fuel tanks. External weapons reduce the Scythe's speed and increase radar cross section, but improve combat capabilities.

The Sky Warrior data-link system allows the B-41 to receive data from ground assets, satellites and other aircraft, while sharing its own radar and targeting data. Thus it can fire its standoff missiles without a direct radar lock on the target. Like the (proposed) B-1R, the B-41 is equipped with an AESA radar and the capability to fire air-to-air missiles. However, it usually uses low altitude, high subsonic speed and a (partially) reduced RCS profile (B-1B standards) to evade enemy defenses.

The Royal South Axiomian Air Force uses the Scythe in a heavy strategic bomber role. All four squadrons have a long-range nuclear delivery role, using the Scythe and its hypersonic standoff missiles to overwhelm North Axiomian (or if required, Russian) interceptors and air defense platforms. However, they may occasionally be called upon to provide tactical air support or attack enemy naval formations.
