A. Mission Description and Budget Item Justification
MK-48 ADCAP (Advanced Capability) Research, Development, Test and Evaluation (RDT&E) program executes incremental development of weapon performance
improvements in two development product areas: (1) Advanced Processor Builds (APBs), and (2) Torpedo Technology Insertions (TIs). This Program Element
(0205632N/0366) is tied to development programs that leverage a joint United States/Australia Armaments Cooperative Project (ACP) to develop MK-48 ADCAP
CBASS; technologies developed by the Office of Naval Research (ONR), and the Office of the Secretary of Defense (OSD) Strategic Capabilities Office (SCO).
Countermeasure (CM) sophistication and availability on the open market directly affects ADCAP kill proficiency and its ability to counter rapidly evolving threats. The
focus of the MK-48 ADCAP Torpedo Research and Development (R&D) program is on hardware upgrades, rapid Commercial-Off-the-Shelf (COTS) insertion, and
software APBs, in order to rapidly upgrade the ADCAP to counter evolving threats and maintain robust performance. The CBASS program developed and fielded a new
sonar capable of identifying CMs and discriminating them from the target. CBASS Phase I achieved IOC in FY 2006. CBASS Phase II achieved IOC in FY13 . APB5
conducted an early fielding decision in May 2019.
The Royal Australian Navy (RAN) is jointly participating to develop MK48 ADCAP upgrades and signed a Memorandum of Agreement (MOA) extension amendment in
January 2019, which extends the MOA for fifteen (15) years.
The MK-48 ADCAP Torpedo R&D program focuses on two specific areas near term; Torpedo software APBs and hardware Tech Insertions (TIs). The CNO continues
to stress shallow water as a critical operating area to counter third world diesel electric submarines and near-peer adversaries. In water testing, in conjunction with
laboratory simulation efforts, has shown that significant performance improvements can be made by implementing changes to weapon tactics and software algorithms.
Development, implementation, and testing of these changes are being accomplished under the Torpedo APB (TAPB) program. The TAPB program also leverages the
RAN joint torpedo program and technologies developed by ONR and SCO in the areas of torpedo broadband signal processing, tactics processing, and alertment.
The TI program will provide for evolutionary torpedo hardware improvements and upgrades, including the transition and testing of advanced technologies from the R&D
community. This approach will incorporate developmental testing of the transitioning technologies from ONR, and SCO for ADCAP upgrades in the areas of torpedo
sensors, weapon propulsion, weapon/platform connectivity, and improved fusing. These efforts will continue torpedo development investment at a lower cost and
shorter term than traditional torpedo programs.
The MK 48 MOD 7 APB6/TI-1 Heavyweight Torpedo (HWT) program is an evolutionary upgrade to the MK 48 MOD 7 HWT; it will consist of an Operational Software
(OPSW) upgrade referred to as APB 6 and a hardware upgrade referred to as TI-1. TI-1 will include a Guidance and Control (G&C) section upgrade, and an Improved
Post Launch Communications System (IPLCS). TI-1 will also include features from three ONR Future Naval Capabilities (FNC) programs.
