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.

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.

The US Army’s Bradley Remanufacture Program

In the 1970s, middle eastern wars demonstrated that tanks without infantry screens were vulnerable to infantry with anti-tank missiles. Unfortunately, armored personnel carriers were easy prey for enemy tanks, and sometimes had trouble just keeping up with friendly tanks like America’s 60+ ton, 50+ mph M1 Abrams. In response, the Americans rethought the armored personnel carrier, taking a page from the Soviet book. They created a more heavily armored, faster “Infantry Fighting Vehicle” named after WW2 General Omar “the soldier’s general” Bradley, and gave it an offensive punch of its own. M2/M3 tracked, armored IFVs can carry infantry – but they also have 25mm Bushmaster cannons, networked targeting sensors, and even TOW anti-armor or Stinger anti-aircraft missiles at their disposal.

Even well-serviced vehicles must suffer the pangs of age and wear, however, and the pace of electronics breakthroughs is far faster than the Army’s vehicle replacement cycle. The US Army plans to keep its Bradley fleet for some time to come, and new technologies have made it wise to upgrade part of that fleet while renewing the vehicles. Hence the remanufacture program, which complements the restore-only RESET programs.

This free-to-view DII Spotlight article explains the differences between the Bradley variants involved, details the re-manufacture process, offers additional research sources, and covers associated contracts from FY 1999 to the present.

The Fighter Still Remains… The Boxer MRAV APC Family

Wheeled armored vehicles have become much more common, but the Dutch-German Boxer stands out from the crowd. Its English acronym is “Multi Role Armoured Vehicle” (MRAV), but rather than being a family of different vehicles, the Boxer will use a single chassis, with snap-in modules for different purposes from infantry carrier to command, cargo, ambulance, etc.

The base vehicle has a maximum road speed of 100 km/h (60 mp/h) and an operational range of 1,000 km (600 miles). In its troop carrying configuration, it has a crew of 2 and can carry 10 fully equipped troops. The MRAV is fighting for space in a crowded market, but its principal countries are beginning to give it the front-line credibility it needs to succeed.

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.

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.

US Military Adds Heavy Trucks Under FHTV-III

In 2009, with its bridge buy of FMTV medium trucks in place, and initial awards for the potential JLTV Hummer replacement designs underway, the next order of business on the US Army’s agenda was a new Family of Heavy Tactical Vehicles multi-year contract: FHTV-III. That multi-billion dollar FHTV-III contract has been awarded – not as a re-compete like FMTV, but as a single-source solicitation.

Oshkosh has provided the core of this capability for over 20 yeas now. Its Heavy Expanded Mobility Tactical Trucks (HEMTT) and their 13-ton payloads are the mainstay of the FHTV fleet, serving in variants that include M977/985 Cargo, M978 Fueler, M982/983 Tractors, and M984 Wrecker/Tow; they also serve as heavy transporters for Patriot and THAAD air defense systems. M1074/75 Palletized Load Systems (PLS) and PLS trailers (PLST) are best known for their automated container/pallet loading arms, and for their Universal Power Interface Kit (UPIK) that can add modules for firefighting, construction, cranes, cement mixing, etc. The M1000/1070 Heavy Equipment Transporters (HET) are flatbeds that can transport a 70-ton Abrams tank – or anything less – in order to save wear and tear on expensive armored vehicles and on the roads. A specialized FHTV truck called the M1977 CBT can even lay bridges. This article details the FHTV-III trucks, and related developments and contracts:

Days of the Jackal: Supacat’s HMT Vehicles

Britain is part of the general push by western countries to field heavier, mine-protected vehicles, via orders for the Mastiff Cougar variant and its smaller 4×4 Ridgback companion. UK forces are also fielding vehicles like the Land Rover WMIK (Weapons Mounted Installation Kit) that have a very different core concept: firepower and visibility over protection. When deployed in mixed groups with more protected vehicles, and used on open terrain like the plains of southern Afghanistan, ‘the porcupine’ (WMIK) has earned enemy respect and commander requests.

The British sought to build on the WMIK’s strengths, while asking for a vehicle that offered both greater firepower, and better off-road mobility. In response, Supacat’s High Mobility Transporter (HMT) was adapted, then adopted, by the British (“Jackal”) and by Australia’s SAS commandos (“Nary”). Success led to more British orders for Jackal 2 and HMT 600 “Coyote” designs, and now Australian Special Forces are adding the new Extenda vehicle to their fleet.

Soldier Battle JTRS: The HMS Radio Set + SANR

The Pentagon’s JTRS (Joint Tactical Radio System) aimed to replace existing radios in the American military with a single set of software-define radios that could have new frequencies and modes (“waveforms”) added via upload, instead of requiring multiple radio types in ground vehicles, and using circuit board swaps in order to upgrade. Trying to solve that set of problems across the entire American military meant taking on a very a big problem. Maybe too big. JTRS has seen cost overruns and full program restructurings, along with cancellation of some parts of the program.

JTRS HMS (Handheld, Manpack & Small Form-Fit) radios, for use by the individual solder, have survived the tumult, and are now headed into production. They offer soldiers more than just improved communications, and have performed in exercises and on the front lines. Now, production is ramping up.

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.
