Mogami-class Frigate Ship Brief

The Mogami-class frigates, also known as the 30FFM, are a class of multi-role guided-missile frigates developed for the Japan Maritime Self-Defense Force (JMSDF). Designed for versatility and efficiency, these ships integrate advanced technologies to fulfill diverse operational roles, including anti-submarine warfare (ASW), anti-surface warfare (ASuW), and mine countermeasures (MCM).

• Displacement: Approximately 5,500 tons (full load)

• Dimensions:

  • Length: 133 meters

  • Beam: 16.3 meters

• Propulsion: Combined Diesel and Gas (CODAG) system, consisting of:

  • 1x Rolls-Royce MT30 gas turbine

  • 2x MAN 12V28/33D STC diesel engines

• Speed: Exceeds 30 knots

• Range: Approximately 6,000 nautical miles at 18 knots

Armament:

• 1x 127mm Mark 45 naval gun

• 2x Remote-controlled Weapon Stations (RWS) with 12.7mm machine guns

• Vertical Launch System (VLS) for surface-to-air missiles (planned future installation)

• 8x Type 17 anti-ship missiles

• Torpedo tubes for ASW

• Decoy launchers and advanced electronic warfare systems

Sensors and Systems:

• Advanced Integrated Command and Control System (AICS)

• Multifunction radar (likely AESA-based)

• Bow-mounted and towed sonar arrays for ASW

• OQQ-25 mine countermeasure sonar system

• UAV and UUV launch and recovery capabilities

Aircraft Facilities:

• A flight deck and hangar capable of supporting a SH-60K helicopter

• Integration of rotary UAVs for reconnaissance and surveillance

Design Features:

• Stealth-enhanced hull design to reduce radar cross-section (RCS)

• Modular construction for cost efficiency and ease of future upgrades

• Automation to reduce crew size, with a standard complement of approximately 90 personnel

The Mogami-class frigates are a cornerstone of Japan's modern naval strategy, providing a flexible and technologically advanced platform to meet the challenges of contemporary maritime security operations.
