Next-Stage C4ISR Bandwidth: The AEHF Satellite Program

Aug 13, 2020 04:58 UTC DII

Latest updates[?]: Lockheed Martin announced that the AEHF-5 protected communication satellite is now in transfer orbit. The launch on August 8 was successful and the AEHF-5 is now responding to the US Air Force's 4th Space Operations Squadron’s commands. According to Lockheed, the squadron began "flying" the satellite shortly after it separated from its United Launch Alliance Atlas V 551 rocket approximately 5 hours and 40 minutes after the rocket's successful 6:13 am ET liftoff. The Advanced Extremely High Frequency 5 or AEHF-5 satellite is the fifth addition to the Air Force’s Advanced Extremely High Frequency constellation. The satellites are built by Lockheed Martin and are used to relay secure communications for the Armed Forces of the United States, the United Kingdom, Canada, and the Netherlands. The first AEHF satellite was launched in 2006 and the most recent, the AEHF-4 in October 2018. The sixth and final AEHF satellite is expected to launch later this year.

Satellite AEHF Concept

AEHF concept

The USA’s new Advanced Extremely High Frequency (AEHF) satellites will support twice as many tactical networks as the current Milstar II satellites, while providing 10-12 times the bandwidth capacity and 6 times the data rate transfer speed. With the cancellation of the higher-capacity TSAT program, AEHF will form the secure, hardened backbone of the Pentagon’s future Military Satellite Communications (MILSATCOM) architecture, with a mission set that includes nuclear command and control. Its companion Family of Advanced Beyond-line-of-sight Terminals (FAB-T) program will give the US military more modern, higher-bandwidth receiving capabilities, and add more flexibility on the front lines. The program has international components, and partners currently include Britain, Canada, and the Netherlands.

This article offers a look at the AEHF system’s rationale and capabilities, while offering insight into some of the program’s problems, and an updated timeline covering over $5 billion worth of contracts since the program’s inception.

Bringing Home the BACN to Front-Line Forces

Jan 24, 2020 04:58 UTC

Latest updates[?]: Northrop Grumman won a $217.2 million modification, which provides for Battlefield Airborne Communications Node payload operation and support for payload equipment and services. Under the contract, Northrup Grumman will support payload equipment and services for the Battlefield Airborne Communications Node, a US Air Force relay and gateway system carried by the EQ-48 and Bombardier E-11A aircraft. The node enables real-time information flow across the battlespace in line-of-sight and beyond-line-of-sight operations. Work will take place in San Diego and at undisclosed overseas locations, with an expected completion date of January 23, 2021.

E-11A, Kandahar

E-11A BACN

In late June 2009, the USAF awarded Northrop Grumman Defense Mission Systems Inc., of San Diego, CA an urgent requirement contract for its Battlefield Airborne Communications Node (BACN) System. Under current plans, Northrop Grumman will help the USAF deploy BACN in up to 4 “E-11” Bombardier BD-700 Global Express (see also BACN-modified photo) ultra-long-range business jets, and in up to 4 EQ-4B Global Hawk Block 20 UAVs, for sustained deployment through 2015.

BACN is an airborne communications relay that extends communications ranges, bridges between radio frequencies, and “translates” among incompatible communications systems. That may sound trivial, but on a tactical level, it definitely isn’t.

WCSP: Mid-Life Upgrade for Britain’s Warrior IFVs

Nov 12, 2019 04:54 UTC

Latest updates[?]: Up-armored Alvis Warrior infantry fighting vehicles (IFVs) have been deployed to Estonia as part of a rotation of the equipment for the UK-led NATO enhanced Forward Presence battlegroup, Jane’s reports. The Warrior tracked vehicle family is a series of British armored vehicles. The Warrior family developed by Alvis Vickers, which is now BAE Systems Land Systems, has been proved in action with the British Army in operations in the Middle East during Desert Storm and Operation Iraqi Freedom and on United Nations duties in Bosnia. Warrior vehicles were also deployed to Afghanistan. The British Army has upgraded its Warriors to extend their service life to 2025. The upgrade included the General Dynamics UK Bowman tactical communications system and the addition of a night fighting capability in the form of the Thales Optronics battle group thermal imaging program. Until now the Warriors on duty in Estonia have been standard vehicles from the British Army training fleet with no theater-specific enhancements. The new Warriors appeared to be fitted with plates along the length of their hulls to defeat high-explosive anti-tank (HEAT) warheads, which British Army sources said is designated Operational Equipment Standard 3 (OES3). This is an evolution of the theater entry standard armored packages developed for the Iraq and Afghan campaigns.

MCV-80 Warrior in Wrap-2 armor

Warrior in “Wrap-2”

Britain’s MCV-80/FV510 Warrior Infantry Fighting Vehicle was produced between 1984 and 1995. Built of all-welded aluminum construction and armed with the 30 mm Rarden cannon, it was designed to destroy enemy armored personnel carriers at ranges of up to 1,500m, while offering a fast, armored battlefield taxi for up to 7 infantry soldiers. These IFVs were pressurized to protect against Soviet chemical and biological weapons, and included a full range of night vision equipment. They served capably during Operation Desert Storm in 1991, were used to maintain the peace in Bosnia/Kosovo, and have found themselves in very high demand on the post 9/11 front lines.

Individual programs have improved some vehicles’ optics, radios, and add-on armor, but keeping the fleet in service until 2035 will require more extensive work. Hence the GBP 1 billion Warrior Capability Sustainment Programme (WCSP). In mid-November 2009, BAE Systems and Lockheed Martin UK submitted their bids, but the decision took almost 2 years. Fielding isn’t expected until 2018, but work proceeds.

India’s Project 75 SSKs: Too Late to Save the Submarine Force?

Sep 23, 2019 04:52 UTC DII

Latest updates[?]: India's Mazagon Dock Shipbuilders Limited (MDL) has delivered another license-built Kalvari or Scorpène Class diesel-electric submarine to the Indian Navy. The vessel, which will be in service as INS Khanderi once commissioned, was handed over on September 19 at a delivery ceremony in Mumbai. Khanderi is the second of six boats ordered under an $3.2 billion contract signed with Naval Group (then known as DCNS) in October 2005 under India's Project 75 submarine program. The program's first-of-class, INS Kalvari , was commissioned in December 2017.

SSK Scorpene OHiggins Cutaway

Scorpene cutaway

India’s submarine fleet currently consists of 16 boats: 10 Russian SSK Kilo (Sindhugosh) Class, 4 locally built SSK U209 (Shishumar) Class, a leased nuclear-powered Improved Akula Class SSN from Russia (INS Chakra), and its own INS Arihant SSBN. Most of the Kilos have been modernized, but readiness rates for India’s existing submarine fleet sits below 40%, and the U209s will have trouble lasting much beyond 2015. With Pakistan acquiring modern submarines, and Chinese submarine building exploding, expanding India’s submarine fleet became an obvious national priority.

In 2005, India confirmed that it would buy 6 Franco-Spanish Scorpene diesel submarines, with an option for 6 more and extensive technology transfer agreements. Unfortunately, 7 years after that deal was signed, “Project 75” has yet to field a single submarine. A poor Indian procurement approach, and state-run inefficiency, are pushing the country’s entire submarine force toward an aging crisis. This DID FOCUS article covers the Scorpene deal and its structure, adds key contracts and new developments, and offers insights into the larger naval picture within and beyond India.

SSDS: Quicker Naval Response to Cruise Missiles

Aug 19, 2019 04:56 UTC

Latest updates[?]: Lockheed Martin won a $56 million deal for combat system engineering support on the Ship Self-Defense System (SSDS). Under the contract, the SSDS combat system engineering agent and software design agent primary deliverables will be SSDS tactical computer programs, program updates and associated engineering, development and logistics products. The contract will manage the in-service SSDS configurations as well as adapt and integrate new or upgraded war-fighting capabilities. Lockheed will perform work in Moorestown, New Jersey and San Diego, California. Estimated completion date is in December.

SSDS

Right now, in many American ships beyond its Navy’s top-tier AEGIS destroyers and cruisers, the detect-to-engage sequence against anti-ship missiles requires a lot of manual steps, involving different ship systems that use different displays. When a Mach 3 missile gives you 45 seconds from appearance on ship’s radar to impact, seconds of delay can be fatal. Seconds of unnecessary delay are unacceptable.

Hence Raytheon’s Ship Self Defense System (SSDS), which is currently funded under the US Navy’s Quick Reaction Combat Capability program. It’s widely used as a combat system in America’s carrier and amphibious fleets. That can be challenging for its developers, given the wide array of hardware and systems it needs to work with. Consistent testing reports indicate that this is indeed the case, and SSDS has its share of gaps and issues. It also has a series of upgrade programs underway, in order to add new capabilities. Managing these demands effectively will have a big impact on the survivability of the US Navy’s most important power projection assets.

SSGN “Tactical Trident” Subs: Special Forces and Super Strike

Jul 02, 2019 04:56 UTC DII

Latest updates[?]: International Marine and Industrial Applicators LLC was tapped with $8.5 million for the accomplishment of preservation and non-SUBSAFE structural repairs and maintenance on USS Michigan or SSGN 727. The deal will provide preservation, structural repairs, anode removal and safety track repair requirements and include all necessary management, material support services, labor, supplies and equipment deemed necessary to perform this work. Non-SUBSAFE means the structural repairs and maintenance are not part of the Submarine Safety Program, a quality assurance program of the US Navy designed to maintain the safety of the submarine fleet. The USS Michigan is the second sub of the Ohio Class of ballistic missile submarines and guided missile submarines. The Michigan was launched on April 26, 1980. It was built to carry the Navy's third generation submarine-launched ballistic missile (SLBM), the Trident C-4. Work under the contract will take place in Bremerton, Washington and is scheduled to be complete by June next year.

Trident II SLBM

From these…

In the aftermath of the START-II arms control treaty, some of the USA’s nuclear-powered Ohio Class SSBN nuclear missile submarines were converted to become long range conventional strike and special operations SSGN “Tactical Tridents.” Four ultra-stealthy Ohio-class SSBNs had their 24 Trident II D-5 nuclear ballistic missiles removed. They were replaced with up to 154 Tomahawk cruise missiles, plus space in the sub for 66-102 special forces troops, special attachments for new Advanced SEAL Delivery System (ASDS) or older Seal Delivery Vehicle (SDV) “mini-subs,” and a mission control center. Unmanned Underwater Vehicles, and even UAVs for aerial operations, are expected to become equally important options over the SSGN fleet’s career.

Navy SEALs Ashore

…to these

These modifications provide the USA with an impressive and impressively flexible set of conventional firepower, in a survivable and virtually undetectable platform, which can remain on station for very long periods of time. As surveillance-strike complexes make the near-shore more and more hazardous for conventional ships, and the potential dangers posed by small groups continue to rise, America’s converted SSGN submarines will become more and more valuable. This updated, free-to-view article covers their origins and timeline, the key technologies involved, contracts from the program’s inception to the present day, with all 4 submarines back in service.

Australia’s Canberra Class LHDs

May 30, 2019 04:52 UTC DII

Latest updates[?]: The Australian Navy was tailed by the Chinese Military as it travelled towards Vietnam on the South Chinese Sea. The HMAS Canberra was ending a three-month-long tour of seven Asian nations involving three other Australian warships, aircraft and more than 1,200 defense personnel. The ships journeyed near islands controversially claimed by Beijing. Defense officials confirmed, that the ships had a "professional" and "friendly" interaction with the People's Liberation Army during Indo-Pacific Endeavour 2019, an Australian Defense Forces regional engagement mission.

LHD Canberra Class Concept Cutaway

Canberra concept

In May of 2006 the Royal Australian Navy announced its decision to expand its naval expeditionary capabilities. HMAS Manoora and Kanimbla would be replaced with substantially larger and more capable modern designs, featuring strong air support. Navantia and Tenix offered a 27,000t Landing Helicopter Dock (LHD) design that resembled the Strategic Projection Ship (Buque de Proyeccion Estrategica) under construction for the Spanish Navy. The DCNS-Thales Australia team, meanwhile, proposed a variation of the 21,300t Mistral Class that is serving successfully with the French Navy.

Navantia’s larger design eventually won, giving the Spanish firm an A$ 11 billion clean sweep of Australia’s “Air Warfare Destroyer” and LHD programs. These 5 ships will be the core of Australia’s future surface navy. The future HMAS Canberra and HMAS Adelaide will be able to serve as amphibious landing ships, helicopter carriers, floating HQs and medical facilities for humanitarian assistance, and launching pads for UAVs or even short/vertical takeoff fighters.

LCAC Hovercraft: US Navy’s Champion Schleppers Get SLEPped

May 13, 2019 04:56 UTC DII

Latest updates[?]: The Navy awarded Rolls-Royce an $8.6 million contract modification in order to procure 10 MT7 marin turbine installation parts kit shipsets for the Landing Craft, Air Cushion (LCAC) 100 class craft. The LCAC 100 will enhance the US amphibious force’s ship-to-shore capacity with a rated load capacity per craft of 74 short tonnes. LCAC-1s have a 60-short tonne-rated payload. The landing craft was originally designated the Ship-to-Shore Connector and is intended to support the rapid movement of Marine expeditionary forces from naval vessels to shore and will be able to tactically deliver personnel and heavy equipment. The LCAC 100 craft consists of four MT7 turbines. The Rolls-Royce MT7 delivers between 4 to 5 MW and shares common core architecture with the AE1107C-Liberty aero engine. The procurement is in support of the Ship-to-Shore Connector Program. An MT7 installation parts kit is one “shipset” consisting of four engine intakes, two right-hand engine exhausts and two left-hand engine exhausts. Work will take place in Indiana and is expected to be finished by January 2021.

LCAC versatility

The US military calls them Landing Craft, Air Cushion (LCAC). They’re high-speed, fully amphibious hovercraft capable of carrying a 60-ton payload (75 tons in overload) over water and land at speeds in excess of 40 knots and a nominal range of up to 200 nautical miles. Carrying equipment, troops, and/or supplies, the LCAC launches from inside the well deck of an amphibious warship, then travels the waves at high speed, runs right through the surf zone near the beach, and stops at a suitable place on land. Its cargo walks or rolls off. The LCAC returns to the surf to pick up more. Rinse. Agitate. Repeat.

LCAC ashore

LCAC, ashore

A total of 91 LCACs were built between 1984-2001, and their design itself dates back to the 1970s. They require regular maintenance, refurbishment, upgrades, and even life extension programs to keep them operational into the future. This free-to-view Spotlight article will covers the program from 2005 forward, tracking contracts and key events.

CEC: Cooperative Engagement for Fleet Defense

May 10, 2019 04:58 UTC DII

Latest updates[?]: Raytheon won a $15.3 million contract in support of the Cooperative Engagement Capability (CEC). The deal includes design agent and engineering service efforts. According to Raytheon, the CEC program provides a sensor network with integrated fire control capability that significantly improves strike force air and missile defense capabilities by coordinating measurement data from strike force air search sensors on CEC-equipped units into a single, integrated real-time, composite track air picture. CEC improves battle force effectiveness by improving overall situational awareness and by enabling longer range, cooperative, multiple, or layered engagement strategies. CEC will be designed to help the military service coordinate measurement data from sensors during strike force air search missions and facilitate battle force situational awareness. Raytheon will perform work in Florida. The scheduled completion date is in September 2022.

CEC Concept

Cooperative Engagement Capability (CEC) is the US Navy’s secret weapon. Actually, it’s not so secret. It’s just that its relatively low price means often leads people to overlook the revolutionary change it creates for wide-area fleet air and ballistic missile defense.

CEC is far more than a mere data-sharing program, or even a sensor fusion effort. The concept behind CEC is a sensor netting system that allows ships, aircraft, and even land radars to pool their radar and sensor information together, creating a very powerful and detailed picture that’s much finer, more wide-ranging, and more consistent than any one of them could generate on its own. The data is then shared among all ships and participating systems, using secure frequencies. It’s a simple premise, but a difficult technical feat. With huge implications.

This DID FOCUS Article explains those mechanics and implications. It will also track ongoing research, updates, and contracts related to CEC capabilities from 2000 forward.

$1.1B to Upgrade Turkish F-16 fleet

May 03, 2019 04:54 UTC

Latest updates[?]: Aselsan introduced another new technology at the IDEF 19 in Istanbul, which started on April 30. The Turkish company showcased an active electronically scanned array (AESA) design that is being pitched for integration on the Turkish Air Force’s F-16 fleet. According to the company, the radar will be able to perform non-co-operative and automatic target recognition, while also featuring protection against radar frequency jamming, and has electronic support and electronic attack functions. Aselsan sees the radar competing with systems such as Northrop Grumman's APG-83 Scalable Agile Beam Radar on the domestic and export market.

F-16

Turkish F-16

The Turkish and US governments signed a letter of offer and acceptance (LOA) on April 26/05 for the $1.1-billion modernization of 117 Turkish Air Force F-16s to a common avionics configuration. December 2006 saw a $635.1 million contract under that framework issued to Lockeed Martin.

The upgrade will create a common avionics configuration for the service’s fleet of F-16 Block 40 and 50 aircraft. More than 200 F-16 aircraft make up the backbone of Turkey’s current fighter fleet. Systems to be integrated on Turkey’s upgraded F-16s include:
