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.

Double-Jointed & Popular: The Bv Family of Infantry Support Vehicles

The BvS10 is the successor to the wildly popular Bv206, 11,000 of which have been sold to 40 countries around the world – including the USA (M978). Readers may have seen these vehicles elsewhere, too, as a number of Bv206s have post-military careers at ski resorts, in industries like mining and logging, etc. The new BvS-10 is larger and more heavily armored; it’s in use in Britain, France and the Netherlands as a key armored vehicle for their respective Marines, has been bought by Sweden, and is under evaluation elsewhere. International interest includes imitators: Singapore’s Bronco ATTC is a BVS10 competitor, and Finland and Norway have their own local Bv206 variants.

What makes this unusual-looking vehicle family and design so popular? They aren’t like Humvees or similar wheeled mainstays. They aren’t full armored personnel carriers, either – they’re armored, but Bv family vehicles can’t take the kind of punishment that a Bradley or LAV can absorb. Instead, the secret to their success lies in a remarkable all-terrain capability, and their ability to fill a rare and critical role: air-portable and amphibious infantry enhancement. These success factors are discussed below, along with contracts and key developments related to this vehicle family.

Turkey & South Korea’s Altay Tank Project

Turkey’s tank fleet is currently made up of American M-48s and M-60s, some of which have been modernized with Israeli cooperation into M-60 Sabra tanks, plus a large contingent of German Leopard 1s and Leopard 2s. That is hardy surprising. America and Germany are Turkey’s 2 most important geopolitical relationships, and this is reflected in Turkey’s choice of defense industry partners. The country’s industrial offset requirements ensure that these manufacturers have a long history of local partnerships to draw upon.

In recent years, however, a pair of new players have begun to make an impact on the Turkish defense scene. One was Israel, whose firms specialized in sub-systems, upgrades, and UAVs. The other is the Republic of [South] Korea, who has made inroads in the Turkish market with turboprop training aircraft, mobile howitzers… and now, main battle tanks.

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.

Marine APCs: Peregrinations of the EFV to ACV to MPC to ACV 1.1

The US Marine Corps’ AAVP7 Amtracs have been their primary ship to shore amphibious armored personnel carrier for a long time; the AAV7A1 was initially fielded in 1972, and underwent a major service life extension program and product improvement program from 1983-1993. The Expeditionary Fighting Vehicle was the USMC’s plan to replace the aging AMTRACS (lit. AMphibious TRACtorS), which saw extensive service deep inland during Operation Iraqi Freedom.

The personnel version of the new EFVs would carry a crew of 3, plus a reinforced rifle squad of 17 combat-loaded Marines. A high-tech weapons station would provide firepower, via a stabilized ATK 30mm MK 44 Bushmaster cannon with advanced sights to replace the AAV’s unstabilized .50 caliber machine gun. A command variant would carry an array of communications and computer systems and staff personnel. The EFV remained the U.S. Marine Corps’ top land acquisition priority, even as its price tag and development issues cut its buy sharply. Push finally came to shove in 2010, however, as the USMC realized that it simply couldn’t afford the vehicle, or its performance.

That begat a new program called the Amphibious Combat Vehicle (ACV), designed to be a more realistic version of the EFV. A Marines version designed for only light water use was called the MPC, which was iced in June 2013. That program was resurrected under increased capabilities pressures as the APC 1.1, which had its coming out party during an industry day in July 2014. A draft RFP was released in November, with hopes that a final RFP would be issued in spring 2015.

$105.7 million was requested for ACV 1.1 research, testing and evaluation.

The APC 1.1 has been examined by the Congressional Research Service, producing this report, which – in a nutshell – says that the program has a few issues, the primary one being the strategic lack of “connectors” allowing equipment onshore. Current options (LCAC, JHSV and LCU 1600) are relatively unprotected.

Digital Abrams: The M1A2 SEP Program

America’s M1 Abrams tanks come in a number of versions. In addition to the M1A1 that is now standard, the US Army is beginning to field its M1 TUSK for urban warfare. It also operates the M1A2 System Enhancement Program (SEP), currently the most advanced standard variant.

This Spotlight article covers the M1A2 Abrams SEP upgrade program, and will be updated and backfilled as new contracts are issued and key events take place.

Have Guns, Will Upgrade: The M109A7 Paladin PIM Self-Propelled Howitzer

The USA’s 155mm M109 self-propelled howitzers (SPH) were first introduced in 1962, as a form of armored mobile artillery that could stand up to the massed fire tactics of Soviet heavy artillery and rockets. They and their companion M992 Armored Ammunition Resupply Vehicles (AARV) have been rebuilt and upgraded several times, most recently via the M109A6 Paladin upgrade.

In the meantime, the Army has re-learned a few home truths. Artillery arrives in seconds rather than minutes or hours, is never unavailable due to bad weather, and cheaply delivers a volume of explosive destruction that would otherwise require hundreds of millions of dollars worth of bombers and precision weapons. Most combat casualties in the gunpowder age have come from artillery fire, and the US Army will need its mobile fleet for some time to come. So, too, will the many countries that have bought the M109 and still use it, unless BAE wishes to cede that market to South Korea’s modern K9/K10 system, or new concept candidates like the KMW/GDLS DONAR. What to do? Enter the Paladin PIM program.

Navistar’s MaxxPro: 1st Place in MRAP Orders

Navistar subsidiary International Military and Government LLC (IMG) in, Warrenville, IL has won billions of dollars in MRAP program contracts, to produce several variants of its blast-resistant vehicles. The Category I MRUV vehicle’s role is similar to a Hummer’s, albeit with more carrying capacity and much more protection. That has become a staple for IMG’s entry, dubbed the “MaxxPro” by its manufacturer. Their collaboration with an Israeli firm who provides up-armored vehicles for the Marines successfully overcame lukewarm initial interest, but even successful survivors of Aberdeen’s tests where challenged to offer enough protection against the ERP class of land mines that began to appear in Iraq.

Nevertheless, the MRAP program became a production race – and Navistar did very well under those competitive terms. In the end the military’s desire for standardization of its fleets exerted something of a gravitation pull on the competition. A July 2007 order vaulted Navistar into 1st place for initial MRAP Program vehicles ordered, but the US Army is divesting many of its vehicles – creating opportunities for foreign buyers…

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.

US Army Moves Ahead with V-Hull Strykers

Under current plans, the 8×8 wheeled Stryker armored vehicle will be the future backbone of 8 US Army and 1 National Guard medium armored brigades. The 5th Stryker Brigade from Fort Lewis, WA was the first Stryker unit sent to Afghanistan, deployed in the summer of 2009 as part of a troop level increase. The brigade was equipped with 350 Stryker vehicles. In the first few months of deployment, they lost 21 soldiers, with 40 more wounded, to IED land mines. The losses prompted the Army to examine modifications to their Stryker vehicles, in order to make them more resistant to land mines.

One result is the Stryker hull redesign, creating the v-hulled Stryker DVH. The US Army is now on pace to order 2 brigades worth, as it moves toward the end of Stryker armored vehicle production.
