LCS: The USA’s Littoral Combat Ships

May 20, 2019 04:54 UTC

Latest updates[?]: Lockheed Martin won a $12.7 million modification for post delivery support of the USS St. Louis. The USS St. Louis or LCS-19 is a Freedom Class littoral combat ship of the US Navy. In December, the Navy christened the ship in Marinette, the 10th Freedom-class LCS built by Lockheed Martin's Fincantieri Marinette Marine. In all, six Freedom Class ships are under construction and two are in the pre-production phase. The company will plan and implement deferred design changes that have been identified during the construction period. The corrections and upgrades are needed to support St. Louis Sailaway and follow-on post delivery test and trials period, the DoD announced on Thursday. Lockheed will perform work within the US and scheduled completion date is in December next year.

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 $35+ 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, the Navy hasn’t been able to reconcile what they wanted with the capabilities needed to perform primary naval missions, or with what could be delivered for the sums available. The LCS program has changed its fundamental acquisition plan 4 times since 2005, and canceled contracts with both competing teams during this period, without escaping any of its fundamental issues. Now, the program looks set to end early. This public-access FOCUS article offer a wealth of research material, alongside looks at the LCS program’s designs, industry teams procurement plans, military controversies, budgets and contracts.

Britain Upgrading Her Dukes [Type 23 Frigates]

Apr 15, 2019 04:54 UTC

Latest updates[?]: The Type 23 frigate HMS Montrose reportedly arrived in Bahrain to start a three-year mission. The Duke Class ship, that was commissioned in 1994 started its 47,000 mile journey six months ago from her home in Plymouth, sailing via the Pacific and Indian Ocean to reach the Gulf. The Montrose will conduct patrols related to drug trafficking in the Indian Ocean, support counter-terrorism and counter-smuggling operations, and work with Middle East and allied Navies to ensure the safety and security of the region. According to the ship’s Commanding Officer, this deployment „marks a significant milestone“ for the UK’s operations in the Middle East.

HMS Sutherland

Britain’s Type 23 Duke Class frigates were originally envisioned as pure anti-submarine vessels, to the extent of being planned with no other armament. The 1982 Falklands War quickly put paid to that idea, however, and the Type 23s would end up being commissioned from 1989-2001 and fitted with a main gun, Sea Wolf short range anti-air missiles, and Harpoon anti-ship missiles to accompany her torpedoes, decoys, et. al. These changes turned the frigates from specialized sub-hunters into versatile multi-role combatants that play a key role in the British fleet. The Royal Navy is set to continue shrinking in size (see esp. diagram) due to rising ship costs, and even though key platforms like aircraft carriers and amphibious ships may be more capable, the mid-tier combat role filled by frigates is not slated for new construction any time soon. As such, upgrading the Navy’s 13 remaining Type 23s to keep them in service is vitally important to Britain’s future force.

As part of those operational upgrade efforts, the Type 23 frigates will receive: Sonar 2087 towed sonars, the Royal Navy’s latest and most sophisticated submarine hunting system (Thales UK, GBP 166 million for machines that go ‘ping!’); Upgraded vertical-launch Sea Wolf Block 2 air defense missiles to help counter supersonic anti-ship missiles (BAE Systems Insyte with MBDA, GBP 300 million); an improved 114mm Vickers Mk 8 Mod 1 main gun, capable of firing long-range ammunition; and a reshaped stern to cut fuel use. Upgrades are also being performed during maintenance periods, some of which are significant to the ship’s overall capabilities. This article covers a number of upgrade efforts, from 2005-2015.

RQ-4 Global Hawk UAVs

Jan 29, 2019 04:50 UTC

Latest updates[?]: The Air Force contracted Space Dynamics Laboratory $18.3 million to support the Republic of Korea’s Global Hawk program. The deal includes tasking, collecting, processing, exploitation, and dissemination (TCPED) capability. The contract provides for the procurement of the TCPED system, spares and support equipment, sustainment support, and system familiarization. The Global Hawk is an unmanned surveillance aircraft by Northrop Grumman. In November 2018 Northrop was contracted to provide contractor logistics support to the Republic of Korea’s Global Hawks. Space Dynamics Laboratory is a nonprofit unit of the Utah State University Research Foundation. It is responsible for the design, fabrications, and operation of sensors on over 400 payloads ranging from aircraft to rocket-borne experiments to space shuttle experiments and satellite-based sensor systems. Work under the current deal will be performed at North Logan, Utah, and is expected to be completed by May 2020. The contract involves Foreign Military Sales to the Republic of Korea.

RQ-4A Global Hawk

Northrop Grumman’s RQ-4 Global Hawk UAV has established a dominant position in the High Altitude/ Long Endurance UAV market. While they are not 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 (GHM-D or BAMS-D) 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 understanding to the new field of maritime surveillance with high-flying UAVs. It’s not just a test program, however, as its remaining drones also deploy to assist the fleet in active operations.

P-8i: India’s Navy Picks Its Future High-End Maritime Patrol Aircraft

Jan 28, 2016 00:52 UTC

Latest updates[?]: India is formally adding four more P-8I aircraft to its Navy fleet in order to bolster their maritime surveillance capabilities. Contracts for the $1 billion deal were inked on Wednesday and will be delivered over the next three years. The long-range patrol craft can also carry an anti-submarine Harpoon missile for ASW missions.

India’s fleet of Soviet-era maritime patrol aircraft has been upgraded, but it needs to be replaced. Indian naval responsibilities are growing, and the 2008 terrorist atrocities in Mumbai made it crystal-clear that control of their coasts was a necessity. Fortunately, they already had a competition underway. In December 2005, after an attempted buy of Lockheed Martin P-3s fell through, India’s navy had floated an RFP for at least 8 new sea control aircraft. Bids from a variety of contenders, including Lockheed Martin, were submitted in April 2007. Subsequent statements by India’s Admiral Prakash suggested that they could be looking for as many as 30 aircraft by 2020.

The plan had been for price negotiations to be completed in 2007, with first deliveries to commence within 48 months. India’s Ministry of Defence has extreme problems with announced schedules, but their existing fleet was wearing out, international requests for India’s maritime patrol help are rising, and Mumbai’s events provided an extra shove. By January 2009, India had picked its aircraft: the 737-derivative P-8i Neptune, a variant of the P-8A that’s readying for service as the P-3’s successor within the US Navy. DID discusses the geopolitical drivers, the current fleet, the known competitors, Boeing’s P-8i, and key contracts and events.

Listening Sticks: US Navy Sonobuoy Contracts

Dec 18, 2015 00:17 UTC

Latest updates[?]: The Naval Air Warfare Center Aircraft Division (NAWCAD) laboratories and the Anti-submarine Warfare Systems program office (PMA-264) rapidly developed a new sonobuoy launching system over the summer and fall which was delivered this November. The new system was developed as the existing system, the S-3, was being retired. A bit of brainstorming resulted in putting two SH-60B launchers on a pallet to roll on and off from a KC-130 tanker operated by the VX-30 Air Test and Evaluation Squadron.

P-8A: Sonobuoy drop

Sonobuoys are used to detect and identify moving underwater objects by either listening for the sounds produced by propellers and machinery (passive detection), or by bouncing a sonar “ping” off the surface of a submarine (active detection). They usually float, or have at least some part of them that does. Specialized sonobuoys can also detect electric fields, magnetic anomalies, and bioluminescence (light emitted by microscopic organisms disturbed by a passing submarine); as well as measuring environmental parameters like water temperature versus depth, air temperature, barometric pressure, and wave height.

Sonobuoys are generally dropped from aircraft or helicopters that are equipped with a means to launch them, and electronic equipment to receive and process data sent by the sonobuoy. They can also be launched from ships. This entry will discuss some of the new sonobuoys in use, and cover related contracts.

Fly and Listen: The AN/AQS-22 ALFS Sonar System

Sep 03, 2015 01:59 UTC

Latest updates[?]: Raytheon will get $33 million to make more AN/AQS-22 Airborne Low Frequency Sonar devices. With options, the contract could be worth as much as $98 million.

MH-60R & ALFS,
Bermuda

The AN/AQS-22 Airborne Low-Frequency Sonar (ALFS) will equip the US Nay’s new MH-60R multi-mission helicopters, serving as their primary anti-submarine sensor. The new FLASH sonar operates using lower frequencies and higher-power waveforms than existing dipping sonars, improving long-range detection. The AQS-22 dipping sonar claims 4x the area coverage of current systems, and includes both active or passive sonar modes to help track, localize, and classify submarines. A winching system with up to 2,500 feet of cable raises and lowers the sonar.

The ALFS system complements the MH-60R’s radar, and works in concert with other equipment including active or passive sonobuoys, signal processing improvements that are especially helpful in shallow water. This Spotlight article highlights ALFS-related contracts from 2002 to the present.

MFTA: The US Navy’s New Towed Array for Naval Detection

May 25, 2015 00:01 UTC

Latest updates[?]: Lockheed Martin has been handed a $27.3 million option for seven TB-37 multi-function towed array (MFTA) production units, as well as auxiliary equipment and support services. The work and production will be split between the US Navy and Japan under a previous Foreign Military Sale. The TB-37 is a potent anti-submarine warfare sensor, with the system offering several enhancements to the AN/SQR-19 Tactical Towed Array System which it replaces. The TB-37 Multi-Function Towed Array is the first new surface ship array to be built for the US Navy in 25 years and is configured as a long array that can be towed behind surface ships for ASW mission sets.

Naval technologies have advanced on many fronts, but one of the most significant is the growing roster of diesel-electric submarines that boast exceptional quietness. Some of the newer AIP (Air-Independent Propulsion) models even have the ability to operate without surfacing for a week or two at a time. In exercises against the US Navy, diesel-electric submarines have successfully ‘killed’ their nuclear counterparts, and in 2006, a Chinese submarine reportedly surprised a US carrier battlegroup by surfacing within it.

The US Navy is slowly moving to beef up anti-submarine capabilities that had been neglected since the end of the Cold War, and other navies are also beginning to adjust. One of the first areas that requires attention is improved detection. That means wider coverage areas, longer baselines, better sonar and other detection systems, and greater use of small unmanned platforms on the surface and underwater. With UUV/USV platforms still maturing, and almost every advanced navy except the Chinese getting smaller due to the cost of new warships, towed systems are a natural place to start.

USA Upgrades Submarine Fleet Acoustics Under A-RCI Program

Sep 30, 2014 17:25 UTC

Latest updates[?]: 5-year Tech Insertion hardware contract for USA and Australia; Background improved to reflect ongoing extrinsic and intrinsic A-RCI program issues.

Acoustic Rapid Commercial-Off-The-Shelf Insertion (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.

This DID Spotlight on ARCI adds a bit more explanation of exactly what the program entails and where its benefits were focused, as well as covers contracts placed under the A-RCI program from FY 2005 onward. 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.

Australia’s Hazard(ous) Frigate Upgrades: Done at Last

Mar 16, 2014 17:54 UTC

Latest updates[?]: Article close-out. Final status of SM-2 upgrades; Why you don't change your freight forwarder's address for US export sales.

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 SEA 1390 project wasn’t what you’d call a success… but Australia accepted their last frigate in 2010, and the 4 remaining ships will serve until 2020.

SSOP: Britain Extends Contracting Innovations to Naval Sensors

May 29, 2013 18:34 UTC

HMS Astute & Type 45

In late May 2013, Thales UK signed a 10-year, GBP 600 million Sensor Support Optimisation Project (SSOP) with the Ministry of Defence. It extends the 2003 Contractor Logistics Support deal that covered electronic warfare/ ESM and sonar system support on an array of submarines and surface ships.

SSOP coverage includes all British submarine classes (SSN Trafalgar and Astute classes, SSBN Vanguard Class), Type 45 Daring Class destroyers, Type 23 Duke Class frigates, and the Hunt and Sandown Classes of minehunting vessels. It also covers all visual systems (periscopes etc.) for all Royal Navy submarines, which had been a separate contract with Thales UK’s optronics business in Glasgow. This progression is familiar to readers who have followed British Future Contracting for Availability practices over the last several years.
