What is the sustained rate of fire determined by ETWD for the M777A2?

The sustained rate of fire for the M777A2 is set at 2 rounds per minute as determined by the Enhanced Tactical Weapon Data (ETWD). This rate is calculated to ensure that the howitzer can maintain effective fire over an extended period without risking overheating or degradation of performance. The sustained rate takes into consideration the operational capabilities of the crew, ammunition logistics, and how quickly a howitzer can safely reload and prepare for subsequent shots.

While the M777A2 can fire at a higher rate during short durations (referred to as the maximum rate of fire), the sustained rate is crucial for prolonged engagements where continuous firing is necessary. This allows artillery units to provide consistent support while managing barrel temperature and maintaining overall weapon integrity.
