Lockheed Martin to Build More Anti-Submarine Warfare (ASW) and Countermine Systems for Surface Warfare Ships

0

WASHINGTON- Underwater warfare experts from the Lockheed Martin Corp. Rotary and Mission Systems in Manassas, Va., will provide the US Navy’s AN/SQQ-89A(V)15 anti-submarine warfare (ASW) systems for surface warfare vessels as part of a Command of $67.9 million announced last week.

Naval Sea Systems Command officials in Washington are requesting Technical Insertion Surface Ship Undersea Combat Systems 20 (TI-20), AN/SQS-53C Transmitter Infrastructure Ship Sets from Lockheed Martin, and spare parts for the AN / SQQ-89A ( Program V)15.

The AN/SQQ-89A(V)15 is an underwater combat system for surface warfare vessels designed to search, detect, classify, locate and track underwater contacts; and to attack or avoid enemy submarines, floating, attached or bottom-mounted 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 submarines, mines and torpedoes hostile.

The countermine and anti-torpedo system provides multi-sensor tracking correlation and target tracking management control, and feeds the data to the ship’s weapons and decision support systems. The AN/SQQ-89A(V)15 works with the ship’s active and passive hull sonar, multi-function towed array, sonobuoy processing, torpedo alerts, fire control system, performance predictions sensors, integrated operator and team training systems.

The AN/SQQ-89A(V)15 has an open electronic architecture to accommodate system upgrades and makes the most of data and system module accessibility, Lockheed Martin officials say. Its software application programs are isolated from hardware with open middleware to make applications processor independent.

The system uses POSIX-compatible system calls and Motif and X-compatible display service calls. Symmetric multiprocessors (SMPs) using Linux-based processing handle signal, data, display, and power processing. interface.

Virtual Network Computing (VNC) enables rapid reassignment of operator console screens depending on the tactical situation, according to Lockheed Martin officials.

Recent and planned upgrades to the AN/SQQ-89A(V)15 include improved automated torpedo detection, sonar performance prediction, advanced active sonar processing, redesigned active displays to reduce load from the operator, as well as integrated training and logistics.

The AN/SQQ-89 is integrated with the Aegis Combat System, Vertical Launch Anti-Submarine Rocket System (ASROC). A variant of the AN/SQQ-89A(V)15 is integrated with the latest version Aegis combat systems installed on board the new Arleigh Burke-class destroyers. A retrofit program is in place to modernize existing DDG-51 class ships and Ticonderoga class cruisers.

On this contract amendment, Lockheed Martin will perform the work in Manassas, Virginia; Lemont Furnace, Pennsylvania; Clearwater, Florida; Syracuse and Hauppauge, NY, and is expected to be completed by August 2024.
