ST. LOUIS, 15 Nov. 2005. Seiler Instrument & Manufacturing Co. in St. Louis won a $5.7 million contract increment Nov. 8 to build optical fire-control units for the Lightweight 155 mm howitzer program.
The Lightweight 155, formerly known as the Advanced Towed Cannon System (ATCAS), replaces all U.S. Marine Corps cannon systems.
The U.S. Army will use the system to support light forces and for the light cavalry regiment replacing all of the M198 155 mm towed howitzers.
The LW 155, which is deployable to any region and can operate in most weather conditions, will provide close and deep fire support and interdiction fire. The system weighs 9,000 pounds -- as light as practical without sacrificing range, accuracy, survivability, and reliability.
Work on the optical fire-control units will be in St. Louis, and should be finished by July 2009. This was a sole source contract awarded last March by the Army Tank-Automotive and Armaments Command at Picatinny Arsenal, N.J. The contract number is W15QKN-06-C-0012.
