Which of the following is listed as a Diamond Storm 2019 aircraft?

• A. F/A-18A/B Hornet
• B. AP-3C Orion
• C. P-8A Poseidon
• D. F-16 Fighting Falcon

Answer: (C)

Diamond Storm 2019 focused on long-range maritime patrol and anti-submarine/warfare capabilities. The P-8A Poseidon fits this role as a modern, high-end maritime patrol aircraft designed for ISR, anti-submarine, and surface surveillance missions, which is why it appears in the exercise roster. Australia’s P-8A Poseidon was chosen to supplement or replace older maritime patrol platforms, aligning with Diamond Storm’s emphasis on up-to-date maritime aviation capability. The other options are not listed for this exercise: the fighter-type F/A-18 is a different mission focus, the AP-3C Orion is the older platform being replaced, and the F-16 is not operated by the Australian forces.
