Aussie Anti-Air Umbrella: The Hobart Class Ships

F100 visits Sydney

Under the SEA 4000 Air Warfare Destroyer program, Australia plans to replace its retired air defense destroyers with modern ships 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 includes area air defense, advanced anti-submarine operations, and the ability to fight other ships.

The Royal Australian Navy took a pair of giant steps in June 2007, when it selected winning designs for its keystone naval programs: Canberra Class LHD amphibious operations vessels, and Hobart Class “air warfare destroyers.” Spain’s Navantia made an A$ 11 billion clean sweep, winning both the A$ 3 billion Canberra Class LHD and the A$ 8 billion 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 2016 or so. A 2014 ANAO report examines why – and the answers aren’t pretty…

P-8 Poseidon MMA: Long-Range Maritime Patrol, and More

P-8A Poseidon

Maritime surveillance and patrol is becoming more and more important, but the USA’s P-3 Orion turboprop fleet is falling apart. The P-7 Long Range Air ASW (Anti-Submarine Warfare) Capable Aircraft program to create an improved P-3 began in 1988, but cost overruns, slow progress, and interest in opening the competition to commercial designs led to the P-7′s cancellation for default in 1990. The successor MMA program was begun in March 2000, and Boeing beat Lockheed’s “Orion 21″ with a P-8 design based on their ubiquitous 737 passenger jet. US Navy squadrons finally began taking P-8A Poseidon deliveries in 2012, but the long delays haven’t done their existing P-3 fleet any favors.

Filling the P-3 Orion’s shoes is no easy task. What missions will the new P-8A Poseidon face? What do we know about the platform, the project team, and ongoing developments? Will the P-3′s wide global adoption give its successor a comparable level of export opportunities? Australia and India have already signed on, but has the larger market shifted in the interim?

AMRAAM: Deploying & Developing America’s Medium-Range Air-Air Missile

Raytheon’s AIM-120 Advanced, Medium-Range Air to Air Missile (AMRAAM) has become the world market leader for medium range air-to-air missiles, and is also beginning to make inroads within land-based defense systems. It was designed with the lessons of Vietnam in mind, and of local air combat exercises like ACEVAL and Red Flag. This DID FOCUS article covers successive generations of AMRAAM missiles, international contracts and key events from 2006 onward, and even some of its emerging competitors.

One of the key lessons learned from Vietnam was that a fighter would be likely to encounter multiple enemies, and would need to launch and guide several missiles at once in order to ensure its survival. This had not been possible with the AIM-7 Sparrow, a “semi-active radar homing” missile that required a constant radar lock on one target. To make matters worse, enemy fighters were capable of launching missiles of their own. Pilots who weren’t free to maneuver after launch would often be forced to “break lock,” or be killed – sometimes even by a short-range missile fired during the last phases of their enemy’s approach. Since fighters that could carry radar-guided missiles like the AIM-7 tended to be larger and more expensive, and the Soviets were known to have far more fighters overall, this was not a good trade…

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.

Kicking it Up a Notch: Poseidon’s Unmanned MQ-4C BAMS Companion

BAMS Operation Concept

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.

Tomahawk’s Chops: xGM-109 Block IV Cruise Missiles

Block IV Cutaway

Block IV Tomahawk is the current generation of the Tomahawk family of cruise missiles. The BGM-109 Tomahawk family began life in the 1980s as sub-sonic, low-flying nuclear strike weapons, before being developed into long-range RGM/UGM-109 conventional attack missiles. They’re most frequently launched from submarines and surface ships, and have been the US Navy’s preferred option for initial air strikes in Iraq, Libya, et. al. Britain has also bought Tomahawk missiles, and launches them exclusively from submarines.

Block IV is the latest variant. It adds innovative technologies that improve combat flexibility, while dramatically reducing the costs to buy, operate, and support these missiles. That’s why the Block IV program, under US Navy PMA-280, has been one of the USA’s defense acquisition success stories over the last decade.

Gulf States Requesting ABM-Capable Systems

Patriot PAC-2

It’s becoming clear that Gulf states, including Saudi Arabia, have stepped up their defense spending in recent years. Uncertainty creates perceptions of risk, and perceptions of risk lead to responses aimed at reducing that risk. That’s why arms spending is an incomplete but very concrete way of tracking a state’s real assessment of threats and priorities. Iraq is no longer a missile/WMD threat, but Iran’s ballistic missiles are another matter. They may be based on North Korean designs that lack accuracy, but the prospect of nuclear payloads is producing reactions.

Gulf states recognize that even a lucky conventional missile could wreak havoc if it hit key oil-related infrastructure, or damaged the larger and more nebulous target of business confidence. The spread of nuclear weapons would change the calculus completely. A 2007 US National Intelligence Assessment [redacted NIE summary, PDF] believed that Iran’s nuclear program had stopped, but others, including the United Nations and Israel, were more skeptical. By 2010, that skepticism had spread to US intelligence, which repudiated an assessment that seems set to join the infamous 1962 NIE of no Soviet missiles in Cuba [1].

The Gulf states’ response to these developments covers a range of equipment, but anti-ballistic missile capabilities appear to be rising to the top of the priority list.

LRASM Missiles: Reaching for a Long-Range Punch

LRASM-A Concept

The US Navy is beginning to acknowledge a growing problem that threatens its freedom of the seas: its strike reach is shrinking and aging, while potential opponents’ attack reach is expanding and modernizing. As new designs replace older planes, US carrier aircraft range is shrinking to 1950s levels. Meanwhile, its anti-ship and land attack missiles are generally older, medium-range subsonic designs like the Harpoon Block I, which are vulnerable to air defenses. In contrast, China is deploying supersonic SS-N-22 “Sunburn” missiles bought from Russia, and working on a DF-21 anti-ship ballistic missile. The Sunburn is just one of Russia’s supersonic anti-ship missile options for sale, and a joint venture with India has added the supersonic PJ-10 BrahMos.

The math is stark: enemies with longer reach, and better weapons, may be able to create large “no go” zones for the Navy in key conflict areas. In response, think-tanks like CSBA are proposing ideas like AirSea Battle, which emphasizes a combination of advance hardening, more stealth and long-range strike options, and a progressive campaign of blinding strikes and grinding interdiction campaigns. Success will require some changes to American weapons, beginning with the missiles that arm its ships and aircraft. Hence LRASM: the Long Range Anti-Ship Missile, with a secondary land-strike role.

Blue Temple Vipers: Indonesia Adding F-16s

TNI-AU F-16A

Indonesia’s purchases of Russian SU-27SK and SU-30MKK Flanker-family fighters in 2003 and 2007 got a lot of attention. Now, the country is augmenting those high-end fighters with more advanced models of an older aircraft within its fleet: 24 refurbished F-16s from the USAF.

The F-16 has a checkered history in Indonesia’s TNI-AU. The Indonesian military’s widespread murders and abuses in East Timor led to a 1999 US arms embargo, which created severe maintenance problems with its 12 remaining F-16A/B Block 15s, and its 16 remaining F-5E/F fighters. The US embargo lifted in November 2005, as lingering concerns about human rights accountability were trumped by the needs of a global campaign against Islamic terrorism. Which left Indonesia wondering what to do about its fighter fleet, as its economy picked up speed.

AMDR: Raytheon is Building the USN’s Next Dual-Band Radar

DBR testbed, Wallops

The US Navy’s Dual-Band Radar that equips its forthcoming 14,500t Zumwalt class“destroyers” and Gerald R. Ford class super-carriers replaces several different radars with a single back-end. Merging Raytheon’s X-band SPY-3 with Lockheed Martin’s S-band VSR allows fewer radar antennas, faster response time, faster adaptation to new situations, one-step upgrades to the radar suite as a whole, and better utilization of the ship’s power, electronics, and bandwidth.

Rather than using the existing Dual-Band Radar design in new ships, however, the “Air and Missile Defense Radar” (AMDR) aimed to fulfill future CG (X)/ DG-51 Flight III cruiser needs through a new competition. It could end up being a big deal for the winning radar manufacturer, and for the fleet. If, and only if, the technical, power, and weight challenges can be mastered at an affordable price.
