The AN/AQS-22 Airborne Low-Frequency Sonar (ALFS) will equip the US Nay’s new MH-60R multi-mission helicopters, and will serve as their primary anti-submarine sensor system. The new FLASH sonar operates at lower frequency and higher power waveforms than existing dipping sonars, which will increase the opportunities for long-range detections; indeed, the AQS-22 dipping sonar claims 4x area coverage compared to current systems and includes both active or passive sonar modes. Submarine tracking, localization, classification are all covered. A winching system with up to 2,500 feet of cable raises and lowers the sonar.

The complete system also includes active or passive sonobuoys, enhanced shallow water capability via processing improvements, and even underwater communication and environmental data collection capabilities.

This Spotlight article highlights ALFS-related contracts since 2002. The latest addition involves a contract to increase the USA’s stock of ALFS systems by 40%...

Trimaran LCS Design

Exploit simplicity, numbers, the pace of technology development in electronics and robotics, and fast reconfiguration. That was the US Navy’s idea for the low-end backbone of its future surface combatant fleet. Inspired by successful experiments like Denmark’s Standard Flex ships, the US Navy’s $30+ billion “Littoral Combat Ship” program was intended to create a new generation of affordable surface combatants that could operate in dangerous shallow and near-shore environments, while remaining affordable and capable throughout their lifetimes.

It hasn’t worked that way. In practice, what the Navy wanted, the capabilities needed to perform primary naval missions, and what could be delivered for the sums available, have proven nearly irreconcilable. The LCS program has changed its fundamental acquisition plan several times since 2005, and canceled contracts with both competing teams, without escaping any of its fundamental issues.

The latest additions include completion of LCS-2 builder tests, and plans to deploy LCS-1 ahead of schedule…

Northrop Grumman’s RQ-4 Global Hawk UAV has established a dominant position in the High Altitude/ Long Endurance UAV market. While they aren’t cheap, they are uniquely capable. During Operation Iraqi Freedom (OIF), the system flew only 5% of the US Air Force’s high altitude reconnaissance sorties, but accounted for more than 55% of the time-sensitive targeting imagery generated to support strike missions. The RQ-4 Global Hawk was also a leading contender in the Broad Area Maritime Surveillance (BAMS) UAV competition, and eventually won.

The Global Hawk Maritime Demonstration Program aims to use the proven RQ-4 Global Hawk airframe as a test bed for operational concepts and technologies that will eventually find their way into BAMS, and contribute valuable operational concepts regarding UAVs in a maritime surveillance role.

Some of that testing took on a decidedly operational bent recently…

DID’s FOCUS articles offer in-depth, updated looks at significant military programs of record. The Royal Australian Navy took a pair of giant steps in June 2007, when it selected winning designs for its keystone naval programs: Canberra Class LHD amphibious operations vessels, and Hobart Class “air warfare destroyers.” This DID’s FOCUS article offers in-depth research and coverage of the Hobart Class competition and program organization, along with the new “air warfare destroyer’s” capabilities, and associated contracts, and related developments.

Under the SEA 4000 Air Warfare Destroyer program, Australia plans to replace its retired air defense destroyers with a modern system that can provide significantly better protection from air attack, integrate with the US Navy and other Coalition partners, offer long-range air warfare defense for Royal Australian Navy task groups, and help provide a coordinated air picture for fighter and surveillance aircraft. Despite their name and focus, the ships are multi-role designs with a “sea control” mission that also includes advanced anti-submarine and surface warfare capabilities.

Spain’s Navantia made an A$ 11 billion clean sweep, winning both the A$ 3 billion Canberra Class LHD and the A$ 8 billion Hobart Class Air Warfare Destroyer contracts. The new AWD ships were scheduled to begin entering service with the Royal Australian Navy in 2013, but that date has now slipped to 2014-2015. Recent updates involve a number of smaller contracts and progress reports, as well as the resolution of A$ 450 million worth of Australian shipbuilding contracts…

HMAS Adelaide

The FFG-7 Oliver Hazard Perry Class frigates make for a fascinating defense procurement case study. To this day, the ships are widely touted as a successful example of cost containment and avoidance of requirements creep – both of which have been major weaknesses in US Navy acquisition. On the other hand, compromises made to meet short-term cost targets resulted in short service lives and decisions to retire, sell, or downgrade the ships instead of upgrading them.

Australia’s 6 ships of this class have served alongside the RAN’s more modern ANZAC Class frigates, which are undergoing upgrades of their own to help them handle the reality of modern anti-ship missiles. With the SEA 4000 Hobart Class air warfare frigates still just a gleam in an admiral’s eye, the government looked for a way to upgrade their FFG-7 “Adelaide Class” to keep them in service until 2020 or so. The A$ 1.46 billion SEA 1390 project has not gone very well… but the new Labor government has just officially accepted the last frigate.

Lockheed Martin Maritime Systems and Sensors in Syracuse, NY received a $15.2 million firm-fixed-price contract for the production of 5 TB-29A thin line towed arrays (TLTAs), which are passive underwater acoustic sensors attached by tow cables to surface ships and submarines. This contract contains options, which, if exercised, will bring its total cumulative value to $29.9 million.

Towed arrays create a longer baseline than other types of underwater sensors, which enhances detection capabilities. According to the 2002 edition of the US Navy’s Vision…Presence…Power: A Guide to U.S. Navy Programs, the TB-29A is a commercial-off-the-shelf (COTS) version of the legacy TB-29 towed array:

In 2005, “Lockheed Receives $76.6M for MH-60S’ New Airborne Anti-Mine Systems” covered several recent advances in US mine detection technologies, including a new AQS-20A mine detecting sonar array, and airborne laser systems mounted to MH-60S helicopters. All of this is in the service of the USA’s new naval emphasis on littoral warfare and accompanying doctrinal changes. So, what’s the AN/AQS-20? And how is it also related to a new US ship class, not to mention a new undersea robot?

The latest news involves its official delivery to the US Navy, in conjunction with its companion AMNS mine neutralizing system…

Alion Science and Technology in McLean, VA received a task order (N00178-04-D-4066) from the US Navy valued at $48.5 million to research, design, develop, prototype, integrate and test a new torpedo detection system in conjunction with the Navy’s anti-torpedo countermeasure technology effort.

The task order, awarded under the Naval Undersea Warfare Center Division Newport’s Seaport-Enhanced (Seaport-e) contract, supports the Naval Sea Systems (NAVSEA) Undersea Defensive Warfare Systems Program Office with anti-torpedo torpedo defensive system (ATTDS) torpedo detection, classification and localization (TDCL) technology.

Seaport-e is a $5.3 billion multiple-award umbrella contract that lets the US Navy use an integrated approach to contracting for support services.

The ATTDS TDCL is a project [PDF] within the Navy’s Surface Ship Torpedo Defense (SSTD) program…

A-RCI is a sonar system upgrade installed on the USA’s entire submarine fleet, including SSN-688 Los Angeles & SSN-688I Improved Los Angeles Class, SSN-21 Seawolf Class, SSN-744 Virginia Class, SSBN-726 Ohio Class nuclear missile boats, and the new SSGN Tactical Trident special ops and strike subs.

The program’s concept is simple: you can upgrade the system, without changing the sensors. By sharply upgrading ship sensor processing, it integrates and improves the boat’s towed array, hull array and sphere array sonars, running more advanced algorithms and providing a fuller “picture” of the surrounding environment. Sometimes, it really is all about what you can do with it. A-RCI’s open architecture concept also make it easier to integrate additional sensors, providing a dual-track improvement option for American submarines.

DID’s Spotlight on A-RCI adds a bit more explanation of exactly what the program entails and where its benefits were focused; then we’ll go on to cover contracts placed under the A-RCI program from FY 2005 onward….
