Mogami uses a conventional propulsion plant, while its compact integrated mast is singled out as an innovative feature that has attracted interest from India and other navies. Its standard fit includes 16 Mark 41 cells, which could hold 64 quad-packed Evolved Sea Sparrow Missiles or a smaller number of larger weapons. Eight Type 17 anti-ship missiles continue Japan's domestic, iterative missile-development path. Mine-laying equipment, torpedoes, a helicopter, and a five-inch gun cover a wide range of fleet and peacetime work. In role and philosophy, the ship resembles an Oliver Hazard Perry or MEKO 200 updated for current threats. Adding every desirable weapon would quickly increase size and cost, so the existing restraint is part of the design's value.
