AEHF concept
(click to view full)

Advanced Extremely High Frequency (AEHF) satellites will support twice as many tactical networks, while providing 10-12 times the capacity and 6 times higher data rate transfer than that of the current Milstar II satellites. They will form the secure backbone of the Pentagon’s intermediate term Military Satellite Communications (MILSATCOM) architecture, until the larger capacity Transformational Communications Satellite System or its equivalent enters service. Its companion Family of Advanced Beyond-line-of-sight Terminals (FAB-T) program, meanwhile, will give the US military modern capabilities and more flexibility on the receiving end.

Like a number of current US satellite development programs, the AEHF program has been cited for cost overruns and schedule slips, in part as a result of failures by the US National Security Agency to furnish key cryptography requirements and specifications in the most timely manner.

In this focus article, DID offers an updated timeline covering over $5 billion worth of AEHF-related contracts, as well as contracts for its FAB-T transmit/receive terminals. Reading it clearly shows many of the issues the program has faced and their financial impacts, as well as some of the new system’s capabilities. The latest news involves another contract to modify the system – this time, it’s the FAB-T receiver terminals…

America’s M1 Abrams tanks come in a number of versions. In addition to the M1A1 that is now standard, the US Army is beginning to field its M1 TUSK for urban warfare. It also operates the M1A2 System Enhancement Program (SEP), currently the most advanced standard variant.

The M1A2 SEP is builds on the digitized M1A2 platform with an improved armor package of third generation steel-encased depleted uranium armor, a new command and control system, second-generation FLIR thermal sights that include a Commander’s Independent Thermal Viewer (CITV) for “hunter-killer” operation, the Under Armor Auxiliary Power Unit (UAAPU) that lets crews run key electronics without running the engine, and a Thermal Management System (TMS – i.e. air conditioning for crew & electronics). The M1A2 SEP also features enhanced electronics like color maps and displays, improved networked communications, high-density computer memory and increased microprocessing speed, a more user friendly “Soldier Machine Interface (SMI)”, and an open operating computing system that will make future upgrades and additions easier.

This DID article covers the M1A2 Abrams SEP upgrade program, and will be updated and backfilled as new contracts are issued and key events take place. New materials will be noted in green. The most recent addition is a long-lead materials contract to get ready for the Third Armored Cavalry Regiment’s tanks…

The entire fleet
(click to view full)

The prime missions of the DDG-1000 Zumwalt Class destroyer are to provide naval gunfire support and next-generation air defense in near-shore areas where other large ships hesitate to tread, possibly even as the anchor for an action group of stealthy Littoral Combat Ships and submarines. The estimated 14,500t (cruiser sized) Zumwalt Class will be fully multi-role, however, with undersea warfare, long-range surface attack, and ballistic missile defense roles. As such, the DDG-1000 is also envisioned as a “hidden ace card” that can use its overall stealth to create uncertainty for enemy forces.

At over $3 billion per ship for construction alone, and just 2-8 ships to be built in the class, the program faces significant obstacles as it tries to avoid either “technology demonstrator” status, or the fulfillment of Secretary of the Navy Donald Winter’s fears for the fleet. A follow-on CG (X) cruiser is currently contemplated, and the success of the DDG-1000 Program will have a significant influence on whether and how it comes to fruition.

This is DID’s FOCUS Article for the DDG-1000 program; it covers the new ships’ capabilities, key controversies, related contracts, and related background resources. From the outset, DID has noted that the Zumwalt Class might face the same fate as the ultra-sophisticated, ultra-expensive SSN-21 Seawolf Class submarines. That appears to have come true, with news of the program’s cancellation at 2 ships.

A recent Congressional Hearing provides in-depth background information re: the DDG-1000 and DDG-51 programs, the decisions that were made, and shipbuilding options between now and the CG (X) cruiser’s debut in 2015 or so. That’s relevant, because the Navy has now reversed course and plans to ask for a 3rd Zumwalt class ship. The question is, will they get it? A recent interview with CNO Adm. Gary Roughead suggests that they may not push very hard if there’s opposition – and also cites anti-submarine warfare deficiencies…

In May of 2006, “Australia Issues Official Tender for A$ 2.0B Large Amphibious Ships Program” covered Australia’s 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 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 LHDs 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.

The latest inclusions involve navigation systems for the ships…

“ROVER” is an unimpressive piece of equipment. Mostly, it looks like a ruggedized laptop with antennas. But SpaceWar.com quotes Lt. Col. Gregory E. Harbin, of the 609th Combat Operations Squadron at Shaw Air Force Base, SC, who says ”...the ROVER is bringing a phenomenal capability to our people on the ground.” ROVER is the Remotely Operated Video Enhanced Receiver, which receives camera images from nearby aircraft and UAVs (somewhat like Israel’s wrist-mounted V-RAMBO), then integrates them with other US positioning and targeting software.

Staff Sgt. Justin Cry, a Shaw Joint Tactical Air Controller (JTAC), has a job that’s an art form at the best of times. Describing features from the ground to a pilot looking down while flying at high speed is no easy task. According to a Dec 16/05 USAF article, he used the system in Iraq and in New Orleans, and says simply: “I can circle an area on my screen, drawing arrows for emphasis, and what I’m drawing appears on (the pilots’) screens as well.”

ROVER continues to evolve, and is becoming an unheralded but critical piece of equipment in America’s arsenal. This is DID’s FOCUS Article covering the system and its ongoing developments – the latest of which is a contract for next-generation ROVER III data links.

In August 2005, “Team Warrior” leader General Atomics Aeronautical Systems, Inc. in San Diego, CA won a $214.4 million cost-plus-incentive-fee contract for research, development, test and evaluation (RDT&E) of the Extended Range/ Multi Purpose Unmanned Aerial Vehicle System (ER/MP UAS). The Warrior was designed to fill both surveillance and attack roles, and the MQ-1C Sky Warrior derived from General Atomics’ famous MQ-1 Predator beat the Hunter II system offered by Northrop Grumman, Aurora Flight Systems, and IAI.

The Sky Warrior ER/MP program is part of the US Army’s reinvestment of dollars from the canceled RAH-66 Comanche helicopter program, and directly supports the Army’s Aviation Modernization Plan. ER/MP could be a $1 billion effort, and recently strengthened its position when a 2007 program restructuring cut the Future Combat Systems Class III UAV competition.

Now, in FY 2008, the MQ-1C Sky Warrior ER/MP prepares to move into production – as the first big “Key West” battle of the 21st century between the USAF and US Army reaches a resolution. But the Sky Warrior and Predator will be merging into a single program. What does that mean, exactly? DID asked. Meanwhile, our readers asked us to explain the differences between the MQ-1 Predator, MQ-1C Sky Warrior, and MQ-9 Reaper. DID is happy to oblige.

The latest news is the acquisition of 3 Block 0 SkyWarriors for use on the front lines…

The Royal Australian Navy took a pair of giant steps toward its future force in June 2007, when it selected winning designs for 2 new Canberra Class LHD amphibious operations vessels, and 3 new Hobart Class air warfare destroyers.

Australia’s ANZAC Class (Meko 200 derivative) and Adelaide Class (FFG-7 Adelaide Class) frigates have limited air defense capabilities. They would be hard-pressed to survive against modern anti-ship missiles, and even planned ANZAC upgrades would not make them suitable for protecting a task force. Under the SEA 4000 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.

After a long campaign that supported the creation and detailed evaluation of 2 fleshed out designs, the A$ 8 billion program has a winner. To the surprise of some observers, Australia’s 3 new “air warfare destroyers” will be… ‘Australianized’ F100 AEGIS frigates. Spain’s Navantia made an A$ 11 billion clean sweep, winning both the Canberra Class LHD and the 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.

This DID FOCUS Article explains the details of the SEA 4000 program, offers some details re: the winning design plus the losing “Evolved DDG-51” option, and covers the contracts and key events to date. Recent events include an update on AEGIS prouction, and a winner for the ships’ sonar system…

Testing, testing…

Perhaps you’ve had this experience with your car. A warning light goes on intermittently, or another system doesn’t seem to operate reliably. The car goes in to the mechanic, where it may or may not display any symptoms. Repeat as required. Eventually, the dreaded diagnosis is given: electrical issues. The problem may or may not be consequential. The fix will be uncertain. The experience will be maddening.

For a military pilot and their maintenance crew, electrical issues are inherently more serious – but no less maddening. Few of us can afford to pay a mechanic for 24 hours of work in order to diagnose an electrical fault, but militaries often do so. Now consider the long-term effects on wiring from the constant airframe vibrations produced by high-energy turbines, and the buffeting produced by travel at several hundred miles per hour. Especially in a machine that may be 30 years old or more, while still possessing some of its original wiring.

As military aircraft fleets continue to age, wiring diagnosis and product improvements will be critical. The F-35 Joint Strike Fighter program is beginning to introduce production innovations involving self-diagnostic wiring, but what about existing aircraft without a full wiring refit? Enter a US NAVAIR project, and a product made by Eclypse International…

Nuclear airbust

L-3 Services, Inc. in San Leandro, CA received a $7.4 million cost-plus-fixed-fee contract for the design, development, integration and production of a form, fit and function, environmentally sealed, state-of-the-art Electromagnetic Pulse (EMP) Pulser and its associated control system. Work will be performed in San Leandro, CA, and is expected to be complete in August 2010. Contract funds in the amount of $1.25 million will expire at the end of the current fiscal year. This contract was competitively procured under an electronic request for proposals, with 2 offers received by the Naval Air Warfare Center Aircraft Division in Patuxent River, MD (N00421-08-C-0070).

EMP is a side-effect of intense radiation bursts, usually from a nuclear weapon. Its effect is to fry most semiconductor-based electronics within its effective range, which is to say most electronics these days. This gives EMP a potential offensive use via strategically placed nuclear airbursts. Rep Roscoe Bartlett [R-MD] has led the charge on this issue in Congress, working to establish an EMP Commission that has reported on the USA’s general vulnerability to such attacks.

The military’s interest in this issue is narrower and more specific. Military systems are checked for their ability to survive specific EMP levels – but to do that, one needs to generate an EMP. Since the exact fate of any one device depends on its resistance, the power of the original pulse, and its distance from the source, testing EMPs from devices like L-3’s pulser can be much smaller – and much closer – than the real thing.

In the 1970s, fighter aircraft began to appear with Head-Up Displays (HUD) that projected key information, targeting crosshairs et. al. onto a seemingly clear piece of glass, so the pilot could keep his eyes on the sky instead of looking down at his instruments. We’ve been wondering when we’d see them in our automobiles ever since. In the 1990s, another innovation appeared: helmet-mounted displays put the HUD inside the pilot’s helmet, providing this information even when the pilot wasn’t looking straight ahead. The Israelis were already using a system called DASH when a set of former East German MiG-29s equipped with HMDs slaughtered USAF F-16s in exercises, and helmet-mounted displays suddenly became must-haves for modern fighters.

The Joint Helmet Mounted Cueing System (JHMCS) projects visual targeting and aircraft performance information on the back of the helmet’s visor, including aircraft altitude, airspeed, gravitational pull, angle of attack, and weapons sighting, enabling the pilot to monitor this information without interrupting the field of view through the cockpit canopy. The system uses a magnetic transmitter unit fixed to the pilot’s seat and a magnetic field probe mounted on the helmet to define helmet pointing positioning. A Helmet Vehicle Interface (HVI) interacts with the aircraft system bus to provide signal generation for the helmet display. This provides significant improvement for close combat targeting and engagement.

A September 2005 exchange with Boeing enabled DID to gain insights into the rocky past, overall state, and future of a program that has experienced its share of snags and controversy – but gone on to become the #1 helmet-mounted sight in the world today. That information fits nicely with DID’s expansion of our coverage to detail the JHMCS’ game-changing effects on air combat, its production sets and known customers, and all contracts since full-rate production began. The latest item is a contract from Boeing to provide the dual-seat version for use in USAF F-15Es…
