Officials of the Naval Sea Systems Command in Washington are asking the Lockheed Martin Rotary and Mission Systems segment in Manassas, Va., to develop, integrate, and produce future advanced capability build and technical insertion baselines of the AN/SQQ-89A(V)15 undersea warfare combat systems.
The AN/SQQ-89A(V)15 is designed to search for, detect, classify, localize, and track underwater contacts, and to attack or avoid enemy submarines, floating, tethered, or bottom-attacked mines, and torpedoes.
The AN/SQQ-89A(V)15 uses active and passive sonar to enable Navy Arleigh Burke-class destroyers and Ticonderoga-class cruisers to detect, locate, track, and attack hostile submarines, mines, and torpedoes.
The system provides multi-sensor track correlation and target track management control, and forwards data to the ship’s weapons and decision-support systems. The AN/SQQ-89A(V)15 works together with the ship's active and passive hull sonar, multi-function towed array, sonobuoy processing, torpedo alerts, fire-control system, sensor performance predictions, embedded operator, and team training systems.
The AN/SQQ-89A(V)15 has an open electronics architecture to accommodate system upgrades, and makes the most of data accessibility and system modules, Lockheed Martin officials say. Its software application programs are isolated from hardware with open middleware to render applications processor-independent.
The system today uses POSIX-compliant system calls and Motif and X-compliant display service calls. Symmetric multi-processors (SMPs) using Linux-based processing handle signal, data, display, and interface processing.
Virtual Network Computing (VNC) enables rapid re-allocation of operator console displays to suit the tactical situation, Lockheed Martin officials say.

Recent and planned upgrades to the AN/SQQ-89A(V)15 include improved automated torpedo detection, sonar performance prediction, advanced active sonar processing, re-designed active displays to reduce operator loading, and integrated training and logistics.
The AN/SQQ-89 is integrated with the Aegis combat system, vertical launch anti-submarine rocket (ASROC) system. A variant of the AN/SQQ-89A(V)15 is integrated with late-version Aegis combat systems being installed onboard new Arleigh Burke-class destroyers. A back-fit program is in place to retrofit existing DDG-51 class ships and Ticonderoga-class cruisers.
On this contract modification Lockheed Martin will do the work in Lemont Furnace, Pa.; Syracuse, Owego, and Hauppauge, N.Y.; Manassas, Va.; Clearwater, Fla.; and Tewksbury, Mass., and should be finished by May 2018.
