Australia’s Pentagon Wars Moment

An Australian MRH-90 helicopter crash in 2023 killed four crew members during a low-level over-water formation exercise for special forces operations. A formal inquiry by the Inspector General of the Australian Defence Force (IGADF) has heard testimony throughout 2024 of considerable disagreement among the test community about the circumstances for approval of the Helmet-Mounted Display Sight used on the fatal mission. Developmental Test and Evaluation (T&E) staff had vigorously opposed using that sight in these flight conditions due to the risk of disorientation leading to commanded flight into terrain. Witnesses have alluded to pressure to accept the sights because they were being tested after purchase. Starting before the crash, for the previous two years Australia's Parliament has been considering a bill to create an independent Defence Capability Assurance Agency, in part, to regulate test and evaluation in such decisions. The United States (US) underwent a similar pivotal movement forty years ago known as the "Pentagon Wars", which was made famous by a book and movie with that name. That movement and the brave and honest testimony of many US test and evaluation staff led to an independent test agency and Title 10 US regulation governing operational and live fire test and evaluation conduct and use in capability decisions. These governance mechanisms are considered the benchmark for credible testing in any allied capability decision. The early evidence from this Australian helicopter crash is diverse and challenging to interpret, however, coupled with the current DCAA Bill, Australia has finally had its inescapable "Pentagon Wars' moment.
