The Navy is ordering torpedo replacement kits from Lockheed Martin Sippican. The firm-fixed-price, cost and cost-plus-fixed-fee modification
has a value of $59.1 million and provides for the production of G&C sections and CBASS kits used on the Mk48 Mod 7 torpedo. The Mk-48 is a huge 533mm torpedo (19 feet long, 3,500+ pounds) with advanced homing, wire guidance capabilities, and devastating consequences when its 300kg warhead hits a target. The Mk48 Mod 7 CBASS
is an upgraded version of the MK 48 Advanced Capability (ADCAP) Mod 6 Advanced Common Torpedo (ACOT). CBASS includes a Broadband Sonar Analog Receiver, preamplifier and interfacing hardware. This gives the retrofitted torpedoes the ability to transmit and receive over a wide frequency band, and takes advantage of broadband signal processing techniques to improve their targeting & tracking capabilities. According to the Lockheed's website
the company delivers at least 20 Mod 7 CBASS kits per month to the US Navy. This contract combines purchases for the US Navy and international allies. The governments of the Netherlands, Canada and Turkey will each receive the kits under the US foreign military sales program. Work will be performed at Lockheed's facilities in Marion, Massachusetts; Braintree, Massachusetts and Lemont Furnace, Pennsylvania. The kits are scheduled for delivery by March 2021.
The Mk-48 is the standard heavyweight torpedo used by the US military, and is mounted primarily on submarines. Surface ships use the smaller Mk46 or Mk50. The Mk-54, in contrast, stemmed from the need for a smaller, lighter, and cost effective advanced torpedo – one that could be dropped from helicopters, planes, and smaller ships. In recent years, the US has moved to modernize and maintain its Mk-48 inventory; the Mk-54 also requires servicing and spares.
Many of these contracts were issued under a total enterprise partnership between Raytheon and the US Navy called Team Torpedo, dedicated to meeting the needs of U.S. and allied naval fleets. Team Torpedo combines Raytheon’s manufacturing, design engineering, and support services expertise with the systems engineering and testing capabilities of Naval Undersea Warfare Center (NUWC) operations in Newport, RI, and Keyport, WA. Now, a new provider has entered the picture.
