• ENGINE & PERFORMANCE
INTRODUCTION
• Lockheed Martin designed and developed the MK 48 Mod 7 Common Broadband
Advanced Sonar System (CBASS) submarine-launched heavyweight torpedo for the US
Navy.
• The torpedo, which has advanced counter-countermeasure capabilities, is operational with
the US and its allied submarine fleet, and serves as a highly effective and lethal weapon
against anti-surface and anti-submarine threats in deep and shallow waters.
• The heavyweight torpedo is equipped with advanced commercial-off-the-shelf technologies
to provide superior reliability and performance against challenging threats in both littoral
and blue water environments, and can support multi-band operation.
DEVELOPMENT
• The MK 48 Mod 7 CBASS is an upgraded version of the MK 48 Advanced
Capability (ADCAP) Mod 6 Advanced Common Torpedo (ACOT),
manufactured by Raytheon.
• The new torpedo was developed as part of an Armaments Cooperative
Programme between the US Navy and the Royal Australian Navy.
• The US Navy awarded a $70.2m contract to Raytheon for 15 MK 48
ADCAP torpedoes in support of MK 48 CBASS initial production and
production engineering.
ODERS & DELIVERIES
• The US Navy awarded a five-year fleet-wide CBASS programme to Lockheed
Martin in 2011 to modernise a total of 1,263 MK 48 torpedoes deployed by the
entire submarine fleet as anti-submarine or anti-surface warfare weapons.
• The company received a contract worth over $50.68m for functional item
replacement kits, engineering services, spare parts and production support material
in March 2011.
• Lockheed Martin was awarded a $10m contract by the Naval Sea Systems
Command (NAVSEA) in April 2014 to provide maintenance support for all MK 48
torpedoes.
DESIGN
• The MK 48 Mod 7 CBASS torpedo has a length of 5.8m and diameter of 53cm,
and can reach a maximum depth of 1,200ft. It weighs 1,676kg and carries a high
explosive warhead of 292.5kg.
• Active and passive homing guidance is provided by the Common Broadband
Advanced Sonar System.
• The torpedo can effectively engage low-Doppler shallow submarines, fast deep
diving submarines and high-performance surface ships.
• The broadband signal processing techniques ensure improved search, acquisition
and attack effectiveness for the torpedo.
ENGINE & PERFORMANCE
•The MK 48 Mod 7 CBASS torpedo is
propelled by an inexpensive Otto Fuel
II Piston engine, and has a speed of
more than 28kt and a range of five
miles.
