It also serves as the foundation of the entire DDG51 curriculum. These include the destruction of enemy cruise missiles, aircraft, surface ships, and submarines and to attack land targets in support of joint or combined operations. The DDG51 class destroyer is designed to be a battle group asset and a multi-purpose surface combatant capable of sustained operations in threat areas outside the umbrella of battle group operations. Helicopter operations on the DDG51 are limited due to the fact that the present ships do not carry their own helos. The ship is able to launch, recover and fuel helos.
Refueling can be a deck refueling or an inflight refueling.
Masker air is used to absorb the noise created by equipment in the main engineering spaces. The air needed for the masker air system is supplied from the bleed air header to the emitter rings around the main spaces. Prairie air is used to reduce the noise created by the ship s propellers as they turn in the water. The air is released from the leading edges of the propeller blades. This air is also supplied by the bleed air system.
