8 Wheelin’ Through ‘Stan

June 13, 2010

The LAV-25 is an eight-wheeled amphibious infantry fighting vehicle (IFV) used by the United States Marine Corps. It was built by General Dynamics Land Systems Canada and is based on the Swiss MOWAG Piranha I 8×8 family of armored fighting vehicles.

 

 Design

Powered by a 6V53T Detroit Diesel turbo-charged engine, they are 4-wheel drive (rear wheels) transferable to 8-wheel drive. These vehicles are also amphibious, meaning they have the ability to “swim”, but are limited to non-surf bodies of water (no oceans). While engaged in amphibious operations, the maximum speed is approximately 12 km/h using equipped propellers. The current SLEP (Service Life Extension Program) modifications will hinder/eliminate amphibious ops.

Typical land speeds are approximately 100 km/h (62.5 mph) in either 4 or 8-wheel drive, however fuel economy decreases in 8-wheel drive. The vehicles operate on diesel fuel, and require 3 weights of lubricants to remain in running condition. They are equipped with a M242 Bushmaster 25 mm cannon, two M240 7.62 mm machine guns, and two 4-barrel grenade launchers usually loaded with smoke canisters and located on the forward left and right sides of the turret. The crew is three; Vehicle commander (VC), gunner and driver, and four passengers (scouts) with combat gear.The vehicle has been through many changes through the late 1990s. The new modification or SLEP has changed the LAV-25 to the LAV-25A1 standard and has been completely fielded.

 Variants

 LAV-25
Standard LAV fitted with a turret with 360° traverse, armed with an M242 25 mm chain gun with 420 rounds of 25 mm ammunition, both M791 APDS-T( Armour Piercing Discarding Sabot-Tracer) and M792 HEI-T (High Explosive Incendiary-Tracer), of which half is ready for use. 150 rounds are ready for use from one stowage bin, 60 from another stowage bin, the other 210 rounds are stowed elsewhere in the vehicle. A coaxial M240C machine gun is mounted alongside the M242, and a pintle mounted M240 G/B machine gun, with 1,320 rounds of 7.62 mm ammunition, is mounted on the turret roof. The Canadian Army uses this chassis for its Coyote Armoured Reconnaissance Vehicle.

LAV-25A2


Funding has been approved for continued upgrades to the LAV family to bring them up to the LAV-A2 standard. Phase I improvements include increased external and internal ballistic armor upgrades, improved fire suppression equipment, and upgrading the vehicle’s suspension to the Generation II standard. Phase II upgrades include replacing the turret hydraulics with an electric drive system and replacing the thermal sight with an improved model incorporating a laser range finder.

To reflect the improved significant survivability and capability enhancements occurring today, the LAV is being renamed as the LAV-A2. The LAV-A2 project involved developing and installing an internal and external ballistic protection upgrade package for the Light Armored Vehicles, an automatic fire suppression system for the interior of the vehicle and a Generation II suspension upgrade to support the added weight of the new armor. The suspension upgrade includes new struts/steering knuckles, torsion bars, shocks and mounts and drive shaft. The three-kit armor system provides the LAV with additional survivability against improvised explosive devices (IED) and direct-fire kinetic energy weapons.

LAV-A2 includes the AN/PAS-13 Improved Thermal Sight System (ITSS) developed by Raytheon of McKinney, TX, scheduled for fielding by the end of 2007. The ITSS provides the gunner and commander with thermal images, an eye-safe laser range finder, a fire-control solution and far-target location target grid information.

The new armor will provide 14.5 mm armor-piercing all around protection for both the crew and passengers of the vehicle, along with anti-spall lining in the vehicle to further protect the crew. It will consist of the same protection as the US Army’s Stryker.

MQ-1 PREDATOR UNMANNED AERIAL VEHICLE

Mission

The MQ-1 Predator is a medium-altitude, long-endurance, remotely piloted aircraft. The MQ-1’s primary mission is interdiction and conducting armed reconnaissance against critical, perishable targets. When the MQ-1 is not actively pursuing its primary mission, it acts as the Joint Forces Air Component Commander-owned theater asset for reconnaissance, surveillance and target acquisition in support of the Joint Forces commander.

Features

The MQ-1 Predator is a system, not just an aircraft. A fully operational system consists of four aircraft (with sensors), a ground control station, a Predator Primary Satellite Link, and approximately 55 personnel for deployed 24-hour operations.The basic crew for the Predator is one pilot and two sensor operators. They fly the aircraft from inside the ground control station via a C-Band line-of-sight data link or a Ku-Band satellite data link for beyond line-of-sight flight. The aircraft is equipped with a color nose camera (generally used by the pilot for flight control), a day variable-aperture TV camera, a variable-aperture infrared camera (for low light/night), and a synthetic aperture radar for looking through smoke, clouds or haze. The cameras produce full motion video while the SAR produces still frame radar images.The MQ-1 Predator carries the Multi-spectral Targeting System with inherent AGM-114 Hellfire missile targeting capability and integrates electro-optical, infrared, laser designator and laser illuminator into a single sensor package. The aircraft can employ two laser-guided Hellfire anti-tank missiles with the MTS ball.The system is composed of four major components which can be deployed for worldwide operations. The Predator aircraft can be disassembled and loaded into a “coffin.” The ground control system is transportable in a C-130 (or larger) transport aircraft. The Predator can operate on a 5,000 by 75 feet (1,524 meters by 23 meters), hard surface runway with clear line-of-sight. The ground data terminal antenna provides line-of-sight communications for takeoff and landing. The PPSL provides over-the-horizon communications for the aircraft.An alternate method of employment, Remote Split Operations, employs a smaller version of the GCS called the Launch and Recovery GCS. The LRGCS conducts takeoff and landing operations at the forward deployed location while the CONUS based GCS conducts the mission via extended communications links.The aircraft includes an ARC-210 radio, an APX-100 IFF/SIF with Mode 4, an upgraded turbo-charged engine and glycol-weeping wet wings  for ice mitigation. The latest upgrade includes fuel injection, longer wings, dual alternators and other improvements.

Background

The “M” is the Department of Defense designation for multi-role and “Q” means unmanned aircraft system. The “1” refers to the aircraft being the first of a series of purpose-built remotely piloted aircraft systems.The Predator system was designed in response to a Department of Defense requirement to provide persistent intelligence, surveillance and reconnaissance information to the warfighter.In April 1996, the secretary of defense selected the U.S. Air Force as the operating service for the RQ-1 Predator system. A change in designation from “RQ-1” to “MQ-1” occurred in 2002 with the addition of the armed reconnaissance role.Operational squadrons are the 11th, 15th and 17th Reconnaissance Squadrons, Indian Springs Air Force Auxiliary Field, Nev.
