P-8A Poseidon

The P-8A Poseidon is Australia’s proven multi-mission maritime patrol aircraft. No. 92 Wing currently commands 12 P-8A aircraft which are operated by No. 11 and No. 292 Squadrons at RAAF Base Edinburgh. The P-8A Poseidon has deployed on a vast number of operations and exercises since its first arrival in 2016, ratifying its high capability to generate effects in its primary roles of:

  • anti-submarine warfare 
  • anti-surface warfare 
  • search and rescue
  • maritime intelligence, surveillance and reconnaissance
  • overland intelligence, surveillance and reconnaissance.

Based on the commercial design of Boeing's 737-800, the P-8A is built specifically as a military aircraft and has been substantially modified to include:

  • a weapons bay
  • under wing and under fuselage hard points for weapons
  • sonobuoy deployment system
  • increased structural strength for low level operations (down to 200ft).

The P-8A Poseidon has an advanced mission system and integrated sensor suite which includes: 

  • a multi-role radar 
  • an electro-optical camera
  • an electronic signal detection system
  • a high-capacity acoustic system
  • an extensive off-board communications suite.

The internal fuel capacity of almost 34 tonnes allows the P-8A to conduct low-level anti-submarine warfare operations more than 2,000 kilometres from base. The P-8A is capable of air-to-air refuelling with the KC-30A Multi-Role Tanker Transport aircraft.
