The USS Avenger (MCM-1) is categorized in the United States Navy as a mine countermeasures vessel. She is the lead ship of her class of 14-strong and the third US Navy vessel to take on the Avenger name. Her class includes the USS Defender (MCM-2), USS Sentry (MCM-3), USS Champion (MCM-4), USS Guardian (MCM-5), USS Devastator (MCM-6) USS Patriot (MCM-7), USS Scout (MCM-8), USS Pioneer (MCM-9), USS Warrior (MCM-10), USS Gladiator (MCM-11), USS Ardent (MCM-12), USS Dextrous (MCM-13 and the USS Chief (MCM-14).

Her outward appearance is characterized by a tripod main mast situated forward on the design and an enclosed funnel structure at center. Her bridge is settled into the upper superstructure just behind the bow while the stern is situated well low with a stepped appearance. Propulsion for the Avenger is brought about through 4 x Waukesha Motors Company diesel engines. The engines rotate twin propellers that themselves offer reversible pitch action. Twin light-load electric motors are also provided as are two individual rudders. Top speed is listed at 14 knots.©MilitaryFactory.com
The USS Avenger is optimally crewed by 81 personnel made up of 6 officers and 75 enlisted crewmembers. Her sensor systems consist of an AN/SSN-2 Precise Integrated Navigation System (PINS), and AN/SQQ-32 Mine Hunting Sonar system, an AN/SPS-55 Surface Radar and an AN/WSN-2 Gyro Compass.

Armament-wise, the Avenger packs a suite of short-range defensive weapons in the form of 2 x 12.7mm Browning M2HB heavy machine guns, 2 x 7.62mm M60 general purpose machine guns and 2 x 40mm MK 19 automatic grenade launchers. For mine-hunting duty - obviously the forte of the Avenger system - the vessel utilizes the AN/SLQ-48(V) Mine Neutralization Systems, the AN/SQL-37(V)3 Magnetic-Acoustic Influence Minesweeping Gear, the Oropesa Type 0, Size 1 Mechanical Sweep Equipment and the MDG 1801 Marconi Magnetometer Degaussing System.

Avenger's original home part was NS Charleston, South Carolina. She was deployed operationally to the Persian Gulf for Operation Desert Storm, earning herself and her crew the Combat Action Ribbon and the Navy Unit Commendation. By 1993, she was given her new homeport at Ingleside, Texas. Since then, she has seen deployment to the Atlantic, Mediterranean and the Pacific.

The USS Avenger was first ordered on June 29th, 1982 and laid down by Peterson Shipbuilders on June 3, 1983. The ship was launched on June 15th, 1985 and officially commissioned on September 12th, 1987. She makes her homeport at Ingleside, Texas and fights under the motto "Dux et Defensor Semitae" meaning "Guide and Defender of the Pathway". As of this writing, the vessel was in active service with the United States Active Naval Reserve Force, Mine Countermeasures Squadron 2 of the US Atlantic Fleet.©MilitaryFactory.com
