USS Bronstein (FF-1037)
Weapon Systems

MK33 3-inch/50-caliber gun

The MK33 3-inch/50-caliber guns were widely deployed on a variety of ships for anti-aircraft protection, but in many instances these mounts have been replaced by the more effective and longer range Vulcan/Phalanx CIWS or NATO Seasparrow missile systems. These guns were carried by most destroyer escorts and fired a 13-pound projectiles about six nautical miles.

Note: Bronstein originally had an addtional 3-inch/50 single mount aft on the fantail that was removed for the installation of the SQS-15 TASS towed array sonnar System. (See photo below)
