RQ-4 Global Hawk UAVs

Dec 27, 2019 04:54 UTC

Latest updates[?]: The first RQ-4B ordered by South Korea has been delivered to Sacheon airbase on December 23. The RQ-4 Block 30 Global Hawk Remotely Piloted Aircraft (RPA) arrived at an Air Force base in Sacheon on the southern tip of the Korean Peninsula earlier in the day. It is the first of a total of four units that South Korea is purchasing from the United States under a 2011 deal. The three others will arrive around the first half of next year, though the schedule is subject to change. The exact timing of their official deployment for operations is not decided, and will not be officially disclosed to the public, an Air Force officer said. As one of the most advanced intelligence-gathering platforms in the world, the long-endurance unmanned aerial vehicle, manufactured by US defense company Northrop Grumman, is capable of performing reconnaissance missions for around 40 hours at a time at an altitude of roughly 20 kilometers.

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.

LCS: The USA’s Littoral Combat Ships

Nov 28, 2019 04:56 UTC

Latest updates[?]: The Naval Sea Systems Command awarded Austal USA a modification for Littoral Combat Ships (LCS) industrial post-delivery availability (IPDA) support for LCS 24. This contract modification is for IPDA efforts for LCS 24. Austal USA will provide shipboard support to implement approved engineering change proposals, approved government-responsible deficiencies identified during test and trials, and crew-related activities and preventative maintenance. Austal will also provide program management support and logistics support for technical documentation affected by the work performed. LCS 24 or USS Oakland is the 12th Independence-variant LCS and the third US Navy ship to be named in honor of Oakland. The ship will be homeported in San Diego naval base. The LCS is designed to operate in near-shore environments and open-ocean. It has the capability to tackle modern coastal threats such as submarines, mines, and swarming small craft. Work will take place in Pittsfield, Massachusetts and estimated completion will be by October, 2020.

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.

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

Oct 30, 2019 04:52 UTC

Latest updates[?]: The Royal Australian Navy's (RAN's) last operational Adelaide Class guided-missile frigate, HMAS Melbourne, was decommissioned in a ceremony held on October 26 at its home port of Fleet Base East, Garden Island in Sydney. During its 27 years in service the 4,260-tonne frigate was deployed on operations to the Middle East eight times and earned battle honors for service in East Timor, the Persian Gulf, and Middle East. The 138-meter warship was the only missile frigate left in the fleet of six, after HMAS Newcastle was decommissioned in June. Her departure will make way for a more modern fleet of warships.

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.

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

Sep 23, 2019 04:56 UTC

Latest updates[?]: The US Navy awarded Lockheed Martin a $24.7 million cost-plus-fixed-fee contract to develop the first production unit fabrication and qualification of the TB-37X Multi-Function Towed Array (MFTA) System. The legacy TB-37/U MFTA is an integral part of the AN/SQQ-89A(V)15 Undersea Warfare Combat System Improvement Program for the Arleigh Burke Class guided missile destroyers (DDG-51), Ticonderoga Class missile cruisers (CG-47) and Zumwalt Class destroyers. The TB-37X MFTA shall incorporate next-generation telemetry to mitigate reliability and obsolescence issues experienced with the legacy TB-37/U MFTA. The TB-37X will be deployed on additional platforms, including Littoral Combat Ship (LCS) and Next Generation Guided Missile Frigates (FFG(X)). Lockheed will perform work in Liverpool, New York; Millersville, Maryland; Marion, Massachusetts; Cleveland, Ohio; and Albuquerque, New Mexico, and is expected to be completed by October 2026.

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.

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

Sep 02, 2019 04:50 UTC

Latest updates[?]: The State Department also approved a FMS to Denmark for nine AN/AQS-22 Airborne Low Frequency Sonar (ALFS) systems and six hundred AN/SSQ-36/53/62 Sonobuoys with support for an estimated cost of $200 million. The AN/AQS-22 ALFS dipping sonar and sonobuoy processing system is the primary anti-submarine warfare sensor of US Navy's MH-60R multi-mission helicopter. It provides mission-critical capabilities, including submarine detection, tracking, localization, classification, acoustic intercept, underwater communication and environmental data collection. The AQS-22 dipping sonar features 4-time greater area coverage than current systems, active or passive sonar modes, active or passive sonobuoys, enhanced shallow water capability, generate high power waveforms and many other advanced characteristics.

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.

Britain Upgrading Her Dukes [Type 23 Frigates]

Aug 21, 2019 04:54 UTC

Latest updates[?]: The crew of the HMS Lancaster moved back on board the ship after a two year overhaul in Devonport, the UK Defense Journal reports. The sip also known as the „Red Rose“ has undergone extensive upgrades mirroring the major changes across the frigate flotilla, such as the new Artisan 3D radar, improved navigational radar and new-generation Sea Ceptor missile system as the ship’s shield against air attack. The Sea Ceptor is a sea-based supersonic missile defense system developed for the British Royal Navy. The system will initially be mounted on Type 23 frigates.The Lancaster will now sail back into her homeport of Portsmouth during December. She will then enter the trials phase. Queen Elizabeth launched the Duke Class Type 23 frigate ship in May 1990.

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.

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.

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.

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.
