TPQ-53 Counterfire Radars: Incoming… Where?

Firefinder radars track the path of incoming shells, rockets, mortars, etc., and calculate the point they were fired from. Raytheon’s TPQ-36 radar is specifically designed to counter medium range enemy weapon systems out to a range of 24 kilometers, while the TPQ-37 can locate longer-range systems, and even surface launched missiles, out to 50 kilometers. Michael Yon, embedded with 1-24 (“Deuce Four”) in Mosul, offered a first hand description of counter-battery radars’ effect on enemy tactics in 2005.

Better radar technologies offer a number of potential advantages for this role, including wider fields of view and less maintenance. Not to mention fewer disruptive, time-sucking false positives for deployed troops. In September 2006, Lockheed Martin began a contract to deliver their “Enhanced AN/TPQ-36” (EQ-36) radars. Despite the close official name and designation, this was a wholly new radar system, from a different company. Orders have begun to accumulate, along with deployments – and, finally, a less confusing designation change to AN/TPQ-53.

FRES: The Future of British Armored Vehicles

Many of Britain’s army vehicles are old and worn, and the necessities of hard service on the battlefield are only accelerating that wear. The multi-billion pound “Future Rapid Effects System” (FRES) aims to recapitalize the core of Britain’s armored vehicle fleet over the next decade or more.

The best one can say is that FRES has gone far better than America’s comparable and canceled “Future Combat System.” That doesn’t mean the rise has been smooth. FRES was spawned by the UK’s withdrawal from the German-Dutch-UK Boxer MRAV modular wheeled APC program, in order to develop a more deployable vehicle that fit Britain’s exact requirements. Those initial requirements were challenging, however, and experience in Iraq and Afghanistan led to decisions that changed an already-late program. So, too, have subsequent budgetary crises…

Australia’s A$ 450M-600M LAND 17 Artillery Replacement

In February 2006 the Australian Government gave first pass approval for the replacement of the ADF’s current 105mm and 155mm artillery pieces with new, more capable, artillery systems that feature improved mobility, protection, range and accuracy. Current systems are all towed, and include the aged 105mm M2A2, the L119 Hamel 105mm Field Gun, and the M198 155mm Howitzer. Options for replacing them include a mix of self-propelled artillery systems and lightweight towed artillery systems under an A$ 450-600 million project known as LAND 17. The project will also examine advanced high precision munitions and a networked command and fire control system.

So, how does this project fit into Australia’s larger defense plans? What’s the expected program timeline? And who are the declared and potential contenders? That matters even more now that the solicitation has been released. DID covers the program, and a number of the confirmed or likely competitors… but one category has now been decided.

Israeli “SPYDER” Mobile Air Defense System – First India, now Vietnam

Israel’s SPYDER air defense system follows a recent trend of using advanced air-air missiles designed for fighter jets as ground-launched surface-to-air missiles (SAM). This truck-mounted system mixes radar and optical tracking with any combination of short to medium-range Derby 4 and ultra-agile short-range 5th generation Python 5 air to air missiles, in order to create a versatile system adapted for a wider range of threats. Hence its inclusion in in our AMRAAM FOCUS article’s “international competitors” section.

India has become the system’s inaugural export customer. SPYDER will reportedly replace India’s Russian-made OSA-AKM/SA-8 Gecko and ZRK-BD Strela-10M/ SA-13 Gopher SAM systems, and the purchase has decisively shelved the Indian DRDO’s failed Trishul project.

More success may be on the way. As India’s Air Force gears up, the Army is reportedly about to follow suit with an even bigger contract.

Flexible G/ATORs: The USMC’s Multi-Mission AESA Ground Radars

The US military’s long run of unquestioned air superiority has led to shortcuts in mobile land-based air defenses, and the US Marines are no exception. A December 2005 release from Sen. Schumer’s office [D-NY] said that:

“Current radar performance does not meet operational forces requirements… consequences could potentially allow opposing forces to gain air and ground superiority in future operational areas.”

One of the programs in the works to address this gap is the AN/TPS-80 G/ATOR mobile radar system. It’s actually the result of fusing 2 programs: the Multi-Role Radar System (MRRS), and Ground Weapons Locator Radar (GWLR) requirements. When the last G/ATOR software upgrade becomes operational, it will replace and consolidate numerous legacy radars, including the AN/TPS-63 air surveillance, AN/MPQ-62 force control, AN/TPS-73 air traffic control, AN/UPS-3 air defense, and AN/TPQ-36/37 artillery tracking & locating radar systems.

USA: $162.7M for Sentinels to Watch the Skies

Improved Sentinel

In September 2011, Thales Raytheon Systems in Fullerton, CA received a $162.7 million firm-fixed-price contract for 56 Sentinel AN/MPQ-64A3 radars, along with associated spares and fielding support. Work will be performed in Fullerton, CA, and Forest, MS, with an estimated completion date of June 1/14. One bid was solicited, with one bid received. The U.S. Army Contracting Command, Redstone Arsenal, AL manages the contract (W31P4Q-11-C-0301).

Their Sentinel radar was to be an integral part of the SL-AMRAAM surface to air missile system, until the US Army decided to assume more battlefield risk and cancel it. Even so, the X-band Sentinel pulse-doppler 3D radars can detect a wide variety of aerial targets, and are being bought for forward area air defense units of the U.S. Army and USMC. Raytheon refers to this buy as Improved Sentinel radars (MPQ-64F1), and conversations with Raytheon personnel confirm that the Pentagon’s “MPQ-64-A3” is the same radar. They also confirm its ability to pinpoint the origin of mortar and artillery fire, and note that its effective range has tripled over the original Sentinel, to 120 km/ 75 miles. Cargo HMMWVs are used as the companion/ towing vehicle, and are equipped with the requisite generator to provide power for the radar.

Updates

September 21/16: Egypt is to receive eight Sentinel AN/MPQ-64F1 radars following the foreign military sale approval by the US State Department. The package, including training and other associative equipment, is estimated to cost $70 million. Once delivered, the Sentinels will work toward improving existing Egyptian air-defense capabilities following a series of aviation disasters over the last year.

Iraq’s New Integrated Air Defense System

The US may have left Iraq in 2012, but that country is a long way from being able to police its own airspace. The country’s air defenses involve just 2 airspace surveillance radars and 3 air-traffic-control radars, plus some Saddam-era anti-aircraft guns. In addition shoddy maintenance jeopardizes a small air fleet, though Iraq’s only armed aircraft are Cessna AC-208Bs.

Their first serious defensive systems will be short-range Pantsir S1 systems from Russia, but now an official export request outlines the backbone of Iraq’s future air defense architecture. If it’s installed, it would give them “a baseline tactical radar and threat intercept capability” with missiles, and eventually with their F-16IQ fighters.

All Together Now: Integrating the US Army’s Disparate Air and Missile Defenses

Army IBCS Concept
(click to enlarge)

Interim design review for IBCS completed. (April 26/10)

The US Army awarded a Northrop Grumman-led team a $577 million, 5-year, cost-plus-incentive-fee/ cost-plus-fixed-fee contract to develop the Integrated Air and Missile Defense Battle Command System (IBCS).

Northrop Grumman beat out a team led by Raytheon. The two teams competed in the preliminary design phase of the program.

IBCS is intended to transform the Army’s disparate air and missile defense systems — each with independent sensing, command-and-control and launching capabilities — into an integrated defense capability. The system will enable the Army to manages all of its air and missile defense systems from 1 command-and-control center.

Northrop Grumman’s winning IBCS design is based on a non-proprietary, open architecture approach…

Algerian Arms Deal Brings Russia $7.5 billion, Gas Market Leverage

Yak-130

A February 2006 report noted that a $4 billion arms sale was brewing between Algeria and Russia involving fighter aircraft, tanks, and air defense systems, with the possibility of additional equipment. Those options came through the following month, as a high-level Russian delegation in Algeria closed up to $7.5 billion worth of arms contracts. The Algerian package remains post-Soviet Russia’s largest single arms deal. As an instructive comparison, annual Russian weapons export orders from all customers were just $5-6 billion per year in 2004 and 2005.

Reuters South Africa quoted Rosoboronexport chief Sergei Chemezov as saying that “Practically all types of arms which we have are included, anti-missile systems, aviation, sea and land technology.” The actual contents of that deal were murky, though DID offers triangulation among several sources to help sort out the confusion. A number of these deals have evolved over time, and other public-source information has helped to sharpen the picture a bit. The subsequent crash of Algeria’s MiG-29 deal, and its ripple effects, are also discussed.

If Necessary, Alone: The Shield of Poland

In the wake of events in Georgia and Crimea, Poland has emerged as NATO’s key eastern bastion. The Tarcza Polski (Shield of Poland) aims to give it an advanced air defense system to match.

Poland’s military rise has been slow, but steady. Smart economic policies have created growth, and a willingness to finance national defense is slowly improving their equipment. Combat deployments abroad to Iraq and Afghanistan have both sharpened training, and highlighted areas that still need fixing. Missile proliferation in the Middle East, American fecklessness, and a rearming Russia have all led Poland to the conclusion that they can no longer depend on old Soviet-era air defense equipment. They need their own advanced national air defense system, which can benefit from allied contributions without being dependent on them.
