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.

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 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.

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 International Wideband Global SATCOM (WGS) Program

The US military needs a bigger data firehose. In an era of streaming data from proliferating UAVs and other persistent surveillance platforms, and the need for control of those systems anywhere in the world, bandwidth is almost as important as fuel. Commercial satellite communications (SATCOM) can fill some of the gaps, but it’s expensive, and may not be available when needed. The Wideband Gapfiller SATCOM (now Wideband Global SATCOM) program began as a way to ease these problems in the near term, but went on to become one of the twin pillars of US military communications, alongside the hardened AEHF constellation. Both satellite types expanded their roles after the super-high bandwidth T-SAT program was canceled. Instead, the USA is adding WGS and AEHF satellites in space, even as it makes both programs multi-national efforts here on earth.

WGS is a set of 13-kilowatt spacecraft based on Boeing’s model 702 commercial satellite. These satellites will handle a significant portion of the USA’s warfighting bandwidth requirements, supporting tactical C4ISR(command, control, communications, and computers; intelligence, surveillance, and reconnaissance); battle management; and combat support needs. Upon its 2007 launch into geosynchronous orbit, WGS Flight 1 became the U.S. Department of Defense’s highest capacity communication satellite. WGS F4, launched in January 2012, offers further improvements, as do satellites from WGS F8. The constellation is set to grow to 10, including international participation.

This is DID’s FOCUS Article covering the WGS program’s specifications, budgets, travails, international partnerships, and contracts, with links to additional research materials.

Heat Vision: US Teen Series Fighters Getting IRST

F/A-18 E/F Super Hornet Block IIs fighters are beginning to enter service with the US Navy and Australia, carrying significantly improved AN/APG-79 AESA radars and other electronic upgrades. Recent years have seen another spreading improvement within global fighter fleets, however: Infra-Red Search & Track (IRST) systems that provide long range thermal imaging against air and ground targets. Most of these deployments have been on Russian (MiG-29 family, SU-30 family) and European (Eurofighter, Rafale, Gripen NG) fighters, or special American exports (UAE’s F-16E/F Block 60 Desert Falcons, Korea & Singapore’s F-15K/SG Strike Eagles).

That absence puts American fighters behind an important curve. This IRST approach can defeat radar stealth in some instances, by focusing on engine exhaust, or on the friction of the aircraft as it powers through the atmosphere. As F-14 pilots will recall, long range electro-optics also offer positive identification, conferring the ability to use a plane’s aerial missiles at their full ranges. Best of all, IRST offers a passive way to locate and target enemy aircraft, without triggering the target’s radar warning receivers. When coupled with medium-range IR missiles like some Russian AA-10 variants, France’s MICA-IR, or even future versions of AMRAAM NCADE, an IRST system offers a fighter both an extra set of medium-range eyes, and a stealthy air-to-air combat weapon. Programs are underway to give some American “teen series” fighters this capability, albeit in a somewhat unusual way.

From Dolphins to Destroyers: The ScanEagle UAV

ScanEagle’s base Insight UAV platform was originally developed by Washington state’s Insitu, Inc. to track dolphins and tuna from fishing boats, in order to ensure that the fish you buy in supermarkets is “dolphin-safe”. It turns out that the same characteristics needed by fishing boats (able to handle salt water environments, low infrastructure launch and recovery, small size, 20-hour long endurance, automated flight patterns) are equally important for naval operations from larger vessels, and for battlefield surveillance. A partnership with Boeing took ScanEagle to market in those fields, and the USMC’s initial buy in 2004 was the beginning of a market-leading position in its niche.

This article covers recent developments with the ScanEagle UAV system, which is quickly evolving into a mainstay with the US Navy and its allies. Incumbency doesn’t last long in the fast-changing world of UAVs, though. Insitu’s own RQ-21 Integrator is looking to push the ScanEagle aside, and new multiple-award contracts in the USA are creating opportunities for other competitors. Can Insitu’s original stay strong?

Saudi Snoops: RSAF Turns to King Airs

In recent wars, a lot of high tech gear has been upstaged by a surprising contender. Countries like the USA, Canada, Britain, Egypt, Iraq, and others are flying low-end turboprop business aircraft fitted with an array of sensors and a small crew. They’re cheap to buy, don’t use technology that makes export approval difficult, and are easy to maintain. Operating them is well within the capabilities of any country with an air force. Their sensors also offer more diversity and power than all but the highest-cost UAVs, in exchange for having just 1/2 to 1/3 of a high-end UAV’s mission endurance. No wonder many countries see them as a good complement to, or substitute for, existing UAV offerings.

Saudi Arabia has the money and clout to buy the expensive stuff. Nevertheless…

Australia’s Troubled E-7A “Wedgetail” AWACS Program

The island continent of Australia faces a number of unique security challenges that stem from its geography. The continent may be separated from its neighbors by large expanses of ocean, but it also resides within a potential arc of instability, and has a number of important offshore resource sites to protect. Full awareness of what is going on around them, and the ability to push that awareness well offshore, are critical security requirements.

“Project Wedgetail” had 3 finalists, and the winner was a new variant of Boeing’s 737-700, fitted with an MESA (multirole electronically scanned array) radar from Northrop Grumman. That radar exchanges the traditional AWACS rotating dome for the E-7A’s “top hat” stationary antenna. That design, and the project as a whole, have run into severe turbulence, creating problems for Boeing earnings, the ADF, and other export orders for the type. DID’s FOCUS articles offer in-depth, updated looks at significant military programs of record. This one covers contracts, events, and key milestones within Australia’s E-7A program, from inception to the current day.
