In 1962 the then Cadillac Gage Company developed, as a private venture, a 4 × 4 light armoured vehicle which could be used for a wide range of battlefield missions such as armoured personnel carrier, weapons platform and reconnaissance vehicle.

The first prototype of this vehicle, called the V-100 Commando, was completed in 1963, with first production vehicles being completed the following year.

The V-100 was widely used in Vietnam for both convoy escort work and for patrolling airbases and other high-value targets. The V-100 was powered by a Chrysler 361 V-8 petrol engine which developed 200 hp and gave the vehicle a maximum road speed of 100 km/h. Gross vehicle weight was 7,370 kg and a maximum of 12 men including the crew could be carried.

The V-100 was supplemented in production by the larger V-200, which was powered by a Chrysler 440 CID petrol engine which developed 275 hp and gave the vehicle a maximum road speed of 96 km/h. Gross vehicle weight of the V-200 was 12,730 kg. The V-200 was sold only to Singapore and is no longer being produced. Versions of the V-200 used by Singapore include: anti-aircraft, with the Swedish SAAB Bofors Dynamics RBS 70 surface-to-air missile system; recovery, fitted with an A-frame at the front of the hull; fire support, fitted with a two-man turret armed with a 90 mm MECAR gun with 7.62 mm coaxial and 7.62 mm anti-aircraft machine guns; and APC, fitted with a two-man turret armed with a 20 mm Oerlikon Contraves cannon, 7.62 mm coaxial and 7.62 mm anti-aircraft machine guns. Cadillac Gage submitted their final proposal for the larger V-200 in April 1968, with the first prototype being completed and ready for trials in April 1969. First batch of V-200 vehicles were delivered to Singapore in July 1970.

There is a separate entry for the more recent LAV-300 (6 × 6) armoured vehicle range. This was developed specifically for the export market and is offered with a similar range of turrets as the latest LAV-150 ST family of vehicles.

In 1984, Kuwait placed an order for 20 V-150 S Commandos and 60 V-300 Commandos. It is believed that all of these were lost during the Iraqi invasion of Kuwait in August 1990.

In 1985, Cadillac Gage announced that production of the V-150 was to cease and that it would be replaced in production by the V-150 S.

In August 1988, US Army Tank Automotive Command placed an order with Cadillac Gage Textron for 14 V-150 S vehicles, at a cost of USD7.014 million, with another 10 ordered in December 1988 at a cost of USD3.113 million.

In 1992, Turkey ordered a total of 124 V-150 S 4 × 4 APCs with first deliveries being made late in 1992.

The first order was for 50 vehicles valued at USD14 million and fitted with turrets, and the second order for 74 vehicles valued at USD25.6 million, 20 of which were supplied in water cannon configuration, 10 are APCs with turrets and 44 standard APCs.

In 1994, Cadillac Gage Textron became part of Textron Marine & Land Systems and the V-150 series was renamed the LAV-150 family. In the following description and variants, the current LAV-150 designation is used.

Production of the LAV-150 was undertaken at the Cadillac Gage Textron facility in Coco, Florida, but production was then undertaken at the new Textron Marine & Land Systems facility in New Orleans, Louisiana.

In mid-1995, it was announced that the US Army Tank-automotive and Armaments Command had awarded the company a contract worth USD2 million for the supply of five LAV-150 ST light armoured vehicles for an undisclosed country in Asia.

By late 2005, total production of the LAV-100/LAV-150/LAV-200 series and variants, amounted to over 3,000 vehicles.

With the type classification of the Cadillac Gage ASV 150 by the US Army in March 1999 and the placing of a five-year production contract, the LAV-150 has been phased out of production. Details of the ASV are given in a separate entry. This is designated M1117 by the US Army and is now in service with Military Police units. An initial batch of 43 stretch M1117s has been supplied to Iraq. Description

The all-welded steel hull of the LAV-150 armoured personnel carrier protects the crew from small arms fire up to 7.62 mm in calibre, overhead blast, shell splinters and Molotov cocktails.

The driver sits at the front of the hull on the left side and has two vision blocks in front of him and one on his left. The vehicle commander sits on the driver's right and has one vision block to his front and one on his right. Both crew members have a single-piece hatch cover over their position that opens to the outside. Early production vehicles had a firing port just behind the driver and commander and each provided with a side vision block.

The troop compartment is behind the commander and driver position, with three infantrymen seated down each side of the hull and one to the rear of the machine gunner's position. They enter and leave the vehicle by two doors in the side of the hull, one on each side. The lower part of the door folds downwards and the upper part, which contains the vision block and firing port, opens to the rear. In each side of the hull, forward of the side door, is a firing port with a vision block over the top. All vision blocks in the LAV-150 have crash pads and spall shields for additional protection.

In the centre of the troop compartment roof is a cupola which can be traversed manually through 360 and has a single-piece hatch cover that opens to the rear. On the forward part of the cupola, which has no observation devices, is a pintle-mounted 7.62 mm machine gun with 200 rounds of ready use ammunition and another 3,000 rounds in reserve in the hull.

There is also a door at the rear of the hull on the right side, with the lower part folding downwards and the upper part, which contains the firing port and vision block, opening upwards. Over the top of the passageway that connects the troop compartment with the rear door is a single-piece circular hatch that opens forwards. A further two seats are provided in this passageway.

The engine compartment is at the rear of the hull on the left side with access panels in the top and side of the hull. The engine cooling system is a conventional automotive water-cooled system utilising a fin and tubed radiator with an additional surge tank for reserve capacity. The engine fan and venturi are designed for maximum airflow efficiency and minimum horsepower draw. The cooling system is capable of operating in ambient temperatures of 130F. The engine compartment has a fire extinguishing system that is operated manually by the driver.

Wherever possible, standard military automotive components are used in the LAV-150, such as the engine, transmission and axles. When originally introduced, the Commando LAV-150 was powered by a Chrysler 361 V-8 petrol engine developing 200 hp at 4,000 rpm coupled to a manual transmission with five forward and one reverse gears and a single-speed transfer case. Late production vehicles have a Cummins V-8 diesel engine that develops 202 hp at 3,300 rpm coupled to an Allison automatic transmission and a two-speed transfer case.

The Allison MD3560 automatic transmission fitted to the latest LAV-150 ST is electronically controlled and has a built in computer that tells the transmission when to shift. All gears are helical to ensure quiet operation and the transmission also has a built in diagnostic system.

The Allison MD 3560 transmission is push button controlled and a small box with the push buttons is mounted in the driver's compartment and connected to the transmission by an electrical cable.

The solid axles have silent locking differentials and the suspension consists of semi-elliptical springs and hydraulic double-acting shock-absorbers with rebound control at each wheel station. Jounce control is by hollow rubber springs at each wheel station. The run-flat tyres, which are capable of operation for a distance of 40 km, have self-cleaning treads. Mounted internally at the front of the hull is a winch with a capacity of 4,536 kg, which has 48.76 m of 9.5 mm diameter cable. All members of the LAV-150 family are fully amphibious, being propelled in the water by their wheels.

Standard equipment on all vehicles includes fuel and water cans, two hand-held fire extinguishers, a pioneer toolset, a tow cable, a breaker bar and lug wrench, a first aid kit, a vehicle toolkit (including an 8,000 kg hydraulic jack stowed inside the vehicle), a pamphlet bag, an oddment box, a slave cable, spare vision blocks and an air compressor with hose.

Optional equipment includes:

  • smoke or smoke/fragmentation launchers

  • a fixed pintle socket for the rear

  • a rear ring mount with a 7.62 mm pintle and cradle

  • a ring mount and cradle for a .50 (12.7 mm) M2 HB machine gun or a 40 mm MK 19 automatic grenade launcher

  • a gun shield for a fixed pintle socket or a ring mount weapon

  • a spotlight for a fixed pintle socket or a ring mount weapon with or without a shield

  • night vision equipment

  • a periscope for the ring mount (standard on 20 mm and 90 mm turret ring mounts)
