NAVAL PLATFORM SYSTEMS
Close-In Weapon System (CIWS)
The Block 1B Surface Mode configuration builds on earlier capabilities with the addition of an Optimized Gun Barrel (OGB) for an improved dispersion pattern and an integrated Forward-Looking Infrared System. The new OGBs are 18 inches longer than the original M61A1 gun barrels, are substantially thicker, and include both a barrel brace and muzzle restraint to improve longevity and projectile dispersion patterns. The Enhanced Lethality Cartridge provides a 50 percent increase in penetration mass. The Phalanx FLIR provides a unique capability to search, track and engage littoral warfare threats while simultaneously providing a significant improvement in ASM engagement ranges.
