As a spiral derivative of the Typhoon Mk 25 Weapon System developed by Rafael, the enhanced Mk 38 Mod 2 is the U.S. Navy's ORDALT choice to upgrade the Mk 38 25-mm Chain Gun. Designed for the mission of ship self-protection, the Mk 38 Mod 2 MGS can be applied to a wide range of different ship classes and platform designs of 50 tons or greater displacement. The system's non-penetrating deck design allows for a variety of potential applications throughout hull and superstructure locations to optimize overall operational effectiveness.
The Mk 38 Mod 2 main weapon is the M242 Bushmaster 25-mm Chain Gun, a proven NATO standard auto cannon with 2.5 km range and selectable rates of fire. The M242 Bushmaster fires all USN-approved 25-mm ammunition at up to 180 rounds per minute, with the Mk 38 Mod 2 providing 168 rounds on-mount.
The Mk 38 Mod 2 system incorporates the service-proven Toplite electro-optical fire control system to optimize effective engagement of enemy targets during day, night and in all weather conditions. Toplite provides 4-axis gimbal stabilization, forward looking infra-red radar with three fields-of-view, a low contrast, low light level color television camera and an eye-safe laser range finder.
The Mk 38 Mod 2 provides for crew safe conditions with a remote operation console located in the Combat Information Center or in other protected ship structure. The operation console consists of the main control panel and a multi-function display that provides a single controller with simple operations in all modes.
For near-term application, Mk 38 Mod 2 has begun installation on board USN surface combatants/amphibious ships. BAE Systems has successfully delivered two initial systems that are aboard the USS Princeton.
The Mk 38 Mod 2 has strong potential for use aboard future platforms such as DDG 1000, the Littoral Combat Ship and the LHA(R), as well as U.S. Coast Guard's Integrated Deepwater System ships.
