Restarting Mk-48 Productionpoised to restart production of its heavyweight antisurface and antisubmarine warfare weapon, the Torpedo Mk-48 MOD 7 Common Broadband Advanced Sonar System (CBASS). The last all-up round torpedo procured by the Navy was the Mk-48 MOD 5 Advanced Capability (ADCAP) in 1996. Since then, the Navy’s strategy has centered around performance upgrades to key guidance and control and propulsion items.
The ADCAP itself was an improvement on the Mk-48 MOD 4 analog design. Further improvements have included the MOD 6 modifications, which consisted of both a guidance system and propulsion upgrade; the MOD 6 Advanced Common Torpedo (ACOT), which added an updated processing card box, paving the way for future improvements; and the MOD 7 CBASS, during which the torpedo was given a new broadband sonar receiver. These modifications, implemented gradually over the past 20 years, have only targeted specific components; the decision to restart production, therefore, is a significant one.
