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.

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

G/ATOR diorama

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.

TPQ-53 Counterfire Radars: Incoming… Where?

EQ-36 concept

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.

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.

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

SPYDER Mobile Firing Unit

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.

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.

Aces High: Judge Upholds 3DELRR Long-Range Ground Radar Challenge

AN/TPS-75

The US Air Force’s AN/TPS-75 radar has been in service since 1968. Threats have evolved, and they want to replace it as their main long-range, ground-based radar for detecting, identifying and tracking aircraft and missiles, then reporting them through the Ground Theater Air Control System. The US Marines are considering a similar move, to replace their own AN/TPS-59s. Hence the USA’s Three-Dimensional Expeditionary Long-Range Radar (3DELRR, pron. “Three Dealer”).

3DELRR is intended to provide up to 35 radars for long-range surveillance, air traffic control, and theater ballistic missile detection. It will correct AN/TPS-75 shortfalls by being easier to maintain, thanks to AESA technology, and by detecting and reporting highly maneuverable and/or stealthy targets. Its improved resolution may even allow it to classify and determine the type of non-cooperative aircraft that cannot or do not identify themselves – a trait that allows faster engagement of hostile planes, and reduces the odds of friendly fire incidents. As long as the program itself can avoid friendly fire from the USA’s budget wars.

Overlander is On! Australia’s A$ 3+ Bn Vehicle Program

Out with the old…

LAND 121 – also known as Project Overlander – is the largest land project in Australia’s Defence Capability Plan. Overall, this is currently estimated as an A$ 7.5 billion (USD $7.6 billion) investment in the Australian Army to replace its fleet of Army trucks, patrol vehicles, trailers and modules. Australia’s “Hardened and Networked Army” meta-program needed to pay attention to these vehicles as well, given an existing fleet that was bought between 1959-1994. As Defence Minister Hill said in 2005:

“Our current fleet is ageing and is becoming more costly to maintain and upgrade. The vehicles will range from lightweight four-wheel drives to heavy trucks and prime movers with interchangeable modules to increase operational flexibility.”

This article looks at Project Overlander, with a particular focus on the major vehicle buys from Phase 3 onward. Some parts of Overlander are even linked to America’s JLTV program, though Australia is also preparing a domestic competitor.
