An Australian Defence Force incident involving a Supacat High Mobility Transporter (HMT) in early October has drawn renewed scrutiny to the fleet, highlighting a history of stability issues with the military vehicle.
The safety concerns follow a rollover in Mount Bundey Training Area, Northern Territory, that killed Corporal Brendan Hannam from the Royal Australian Regiment and injured five other soldiers, prompting Canberra to ground the entire fleet.
Hannam, an experienced commando and two-time Afghanistan veteran, is the fourth Australian warfighter killed in similar mishaps in five years.
Series of Accidents
Despite initial claims by Chief of Army Lt. Gen. Susan Coyle that the vehicle type had no prior safety issues, defense officials later acknowledged a 2020 driver training accident.
An insider told ABC Australia that the separate event is classified as a “lay over,” stating the HMT flipped onto its side without making a full rotation onto its roof.
Separately, four-wheel HMT models used by the British Armed Forces have logged over 30 rollovers, including a fatal 2019 crash.
A UK military inquiry then cited the lack of rollover protection on the vehicles in 2021 and recommended urgent structural safety upgrades alongside operational adjustments.
Probe Ongoing
Australian Defence Minister Richard Marles ordered a force-wide review into safety protocols, risk settings, and fatigue management immediately after the October casualty.
“We need to be making sure every lesson that can be learned from this incident is learned,” Marles said.
Meanwhile, officials declined to detail potential modifications to Australia’s 89 Extenda-model Supacats, citing ongoing investigations into the Northern Territory crash.
The Extenda is a modular HMT platform that converts between 4×4 and 6×6 configurations.
The vehicle was previously spotted during operations at Mount Bundey earlier this year.
