From Vietnam war radar service to modern overlanding, ARN 111-387 has lived an extraordinary life. Next stop: Brisbane to Birmingham in 2027.
Our Landy left the UK production line as Car# 153001027, which breaks down as:
1 = Land Rover
53 = Series 2, 109-inch wheelbase, Petrol Engine, RHD
0 = Model Year 1960
01027 = 1027th vehicle produced that year.
Engraved data on the army compliance plate indicates this Series 2 entered the Australian Army in June 1960. It was assigned under Contract Number C104337—the very first Australian military order exceeding 1,000 vehicles, originally signed in December 1958.
Official Australian Defence Force records document ARN 111-387 as a "Truck, Flatbed, 3/4 Ton, GS, Radar Set AN/KPQ1, No 2 Loading." This 1960 LWB Series 2 originally ran on 7.50/16 tyres (re-fitted during restoration) and was officially discharged in NSW on December 6, 1983.
The AN/KPQ-1 mortar-locating radar system was vital for tracking incoming mortar trajectories and calculating counter-battery firing coordinates during active military deployment.
Deployed to Vietnam in late 1960, ARN 111-387 was customized for specialized communications and electronics duty. Key modifications included converting electrical circuits to Negative Earth, fitting military blackout lighting, sealing the key ignition in favor of a heavy-duty push-button, and running thick 2AWG copper power cables. Today, those same historic power cables supply the modern starter motor and dual-battery auxiliary charging system.
Technical Archaeology
While standard Series 2 vehicles were general utility haulers, ARN 111-387 was structured specifically for mobile counter-mortar electronic operations.
Serving as the communications backbone for a Radar Detachment, the flatbed setup provided a stable, wide cargo floor designed to carry thick interconnecting cable spools and the antenna mounting tripod for immediate deployment.
Specialized heavy-gauge wiring provided high-amperage power directly to the radar computing units. Furthermore, ARN 111-387 was reinforced to tow the dedicated radar antenna trailer.
To survive monsoon downpours and red dust, heavy canvas top covers protected sensitive gear, while removable door tops and folding windscreens provided maximum airflow for the crew.
| Specification | ARN 111-387 Setup |
|---|---|
| Body Style | Flatbed / Chassis-Cab |
| Primary Payload | AN/KPQ-1 Cables & Tripod |
| Towing Task | Radar Antenna Trailer |
| Operational Role | Counter-Mortar Support |
Retirement Years
Following military discharge in 1983, the vehicle worked on an agricultural property in New South Wales. During this period, the original 2.25L 4-cylinder engine was swapped for a Holden 202 (6-cylinder "Red Motor") paired with 3.54:1 differential ratios to increase road speed and torque output.
When adapted for farm work, a rear tub, side panels, and roof were fitted over the original flatbed chassis, while preserving the military dashboard, blackout switches, and rear differential blackout paint.
Barn Find Resurrection
By the late 1990s, the Landy was relocated to Queensland. After severe mechanical failure around 2006, it sat parked under a tree in Dalby for over 15 years. In 2023, it was acquired for $2,500 AUD to begin a complete mechanical restoration.
Overland Restoration
In September 2023, the vehicle was recovered and brought to the workshop. The seized Holden engine was replaced with a fully reconditioned Land Rover 2.25L Petrol engine, paired with 3.54:1 diffs for efficient long-distance highway cruising and low-RPM range operations.
We are actively researching the military service record of ARN 111-387. If you served with the 131st Divisional Locating Battery or have historical photographs of this vehicle in Vietnam, please reach out to us.
