E-2D Hawkeye: The Navy’s New AWACS

Northrop Grumman’s E-2C Hawkeye is a carrier-capable “mini-AWACS” aircraft, designed to give long-range warning of incoming aerial threats. Secondary roles include strike command and control, land and maritime surveillance, search and rescue, communications relay, and even civil air traffic control during emergencies. E-2C Hawkeyes began replacing previous Hawkeye versions in 1973. They fly from USN and French carriers, from land bases in the militaries of Egypt, Japan, Mexico, and Taiwan; and in a drug interdiction role for the US Naval Reserve. Over 200 Hawkeyes have been produced.

The $17.5 billion E-2D Advanced Hawkeye program aims to build 75 new aircraft with significant radar, engine, and electronics upgrades in order to deal with a world of stealthier cruise missiles, saturation attacks, and a growing need for ground surveillance as well as aerial scans. It looks a lot like the last generation E-2C Hawkeye 2000 upgrade on the outside – but inside, and even outside to some extent, it’s a whole new aircraft.

Taiwan’s Force Modernization: The American Side

Despite China’s ominous military buildup across the strait, key weapons sales of P-3 maritime patrol aircraft, Patriot PAC-3 missiles, and diesel-electric submarines to Taiwan had been sabotaged by Taiwanese politics for years – in some cases, since 1997. The KMT party’s flip-flops and determined stalling tactics eventually created a crisis in US-Taiwan relations, which finally soured to the point that the USA refused a Taiwanese request for F-16C/D aircraft.

That seems to have brought things to a head. Most of the budget and political issues were eventually sorted out, and after a long delay, some major elements of Taiwan’s requested modernization program appear to be moving forward: P-3 maritime patrol aircraft, UH-60M helicopters, Patriot missile upgrades; and requests for AH-64D attack helicopters, E-2 Hawkeye AWACS planes, minehunting ships, and missiles for defense against aircraft, ships, and tanks. These are must-have capabilities when facing a Chinese government that has vowed to take the country by force, and which is building an extensive submarine fleet, a large array of ballistic missiles, an upgraded fighter fleet, and a number of amphibious-capable divisions. Chinese pressure continues to stall some of Taiwan’s most important upgrades, including diesel-electric submarines, and new American fighter jets. Meanwhile, other purchases from abroad continue.

The USA’s E-6 Fleet: Take Charge, And Move Out!

The USA’s E-6 Mercury (aka. TACAMO, as in TAke Charge And Move Out) “survivable airborne communication system” airplanes support their Navy’s SSBN ballistic missile submarine force and overall strategic forces. With the advent of the new “Tactical Trident” converted Ohio Class special operations subs, their unique capabilities become even more useful. The E-6B version also has a secondary role as a “Looking Glass” Airborne National Command Post, and in recent years they have seen use as communications relay stations over the front lines of combat.

Delivery of the first production E-6 aircraft took place in August 1989, with delivery of the 16th and final airplane coming in May 1992. This is DID’s FOCUS Article concerning the E-6 system, which includes details concerning the capabilities and associated contracts. The latest contracts involve important fleet upgrades, as the Navy tries to drag the jet’s systems into the 21st century.

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

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.

The MQ-4C Triton: Poseidon’s Unmanned Herald

The world’s P-3 Orion fleets have served for a long time, and many are reaching the end of their lifespans. In the USA, and possibly beyond, the new P-8 Poseidon Multi-mission Maritime Aircraft will take up the P-3’s role. While the P-8’s base 737-based airframe offers strong service & maintenance arguments in its favor, the airframe is expensive enough that the P-3s cannot be replaced on a 1:1 basis.

In order to extend the P-8 fleet’s reach, and provide additional capabilities, the Poseidon was expected to work with at least one companion UAV platform. This DID FOCUS Article explains the winning BAMS (Broad Area Maritime Surveillance) concept, the program’s key requirements, and its international angle. We’ll also cover ongoing contracts and key events related to the program, which chose Northrop Grumman’s navalized MQ-4C Triton Global Hawk variant.

ER/MP Gray Eagle: Enhanced MQ-1C Predators for the Army

Its initial battles were fought within the Pentagon, but the US Army’s high-end UAV has made its transition to the battlefield.

The ER/MP program was 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. The US Air Force saw this Predator derivative as a threat and tried to destroy it, but the program survived the first big “Key West” battle of the 21st century. Now, the MQ-1C “Gray Eagle” is in production as the US Army’s high-end UAV. As CENTCOM’s wars end, however, the Gray Eagle may find that staying in the fleet is as hard as getting there.

This FOCUS article offers a program history, key statistics and budget figures, and ongoing coverage of the program’s contracts and milestones.

Future GPS: The USA’s GPS-III Programs

GPS-III satellites, in conjunction with their companion OCX ground control, system are the Global Positioning System (GPS) future. They offer big advantages over existing GPS-II satellites and GCS, but most of all, they have to work. Disruption or decay of the critical capabilities provided by the USA’s Navstar satellites would cripple both the US military, and many aspects of the global economy.

The time-based GPS service is the most-used application of Einstein’s Theories of Relativity. GPS has become part of civilian life in ways that go go far beyond those handy driving maps, including crop planting, timing services for stock trades, and a key role in credit card processing. At the same time, military class (M-code) GPS guidance can now be found in everything from cruise missiles and various precision-guided bombs, to battlefield rockets and even artillery shells. Combat search and rescue radios rely on this line of communication, and so does a broadening array of individual soldier equipment.

This DII FOCUS article looks at the existing constellation, GPS-III improvements, the program’s structure, its progress through contracts and key milestones, and extensive PTN (Positioning, Timing & Navigation)/ GNSS (Global Navigation Satellite System) research links.

SSDS: Quicker Naval Response to Cruise Missiles

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.

Next-Stage C4ISR Bandwidth: The AEHF Satellite Program

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.

The Wonders of Link 16 For Less: MIDS-LVTs

What one sees, all see. Jam-resistant Link-16 radios automatically exchange battlefield information – particularly locations of friendly and enemy aircraft, ships and ground forces – among themselves in a long-range, line-of-sight network. For example, air surveillance tracking data from an Airborne Warning and Control System (AWACS) aircraft can be instantly shared with fighter aircraft and air defense units. More than a dozen countries have installed Link 16 terminals on over 19 different land, sea, and air platforms, making it an interoperability success story.

While recent advancements may make AESA radars the future transmitters of choice, Link 16 is the current standard. The Multifunctional Information Distribution System-Low Volume Terminals (MIDS LVTs) were developed by a multinational consortium to provide Link 16 capability at a lower weight, volume, and cost than the Joint Tactical Information Distribution System (JTIDS). This free-to-view DID Spotlight article throws a spotlight on the program, explaining Link 16, and covering associated contracts around the world.
