Each ship, A, B, and C, is constrained with a specific power architecture designed for its mission requirements. This may limit the adaptability of any of ships A, B, or C for different missions. Such limitations may further apply within a class of ships. For example, two military ships A1 and A2, one a destroyer and one a cruiser, are typically defined in mission scope and in adaptability, in part at least due to their fixed, specific power architectures.

No Manning Required Ships (NOMARS): Naval ships and other vessels are diverse in design and include “no manning required ships (NOMARS)”. Such ships may be unmanned ships with adaptable, flexible mission requirements, and (potentially) with adaptable configurations of power sources and loads. (For example, power sources and loads may be changed when such a ship is in dock.) Such NOMARS ships, in addition to various advantages that accrue from being unmanned during operations, may also be more adaptable for a range of peace-time military, battle-military, and even strictly commercial or civilian missions.

Power Systems for NOMARS: To assure maximum mission adaptability, NOMARS will require an integrated and flexible power generation and distribution system, which is adaptable to various power/energy sources (prime movers/gensets, solar PV, energy storage etc.) and to a variety of loads (AC, DC, pulsating, continuous, and UPS etc.). Critical characteristics/features of such NOMARS power systems, adaptable for diverse missions, include modularity and adaptability based on (operation and health) conditions of the ship and the situation/environment the ship is in.
