Yes that would be rational. It is likely Mckay is aware of the US motives for the P8 programme.

The P-8's predecessor, the Lockheed P-3 Orion ASW aircraft has been in service with the U.S. Navy since 1961. In the mid-1980s the Navy began studies for a replacement aircraft for the P-3 which has lost range/time on station capabilities due to increasing weight and is approaching the end of its fatigue life.
All too often politicians exploit general ignorance of the reality of metal fatigue in dynamic structures such as aircraft, ships, bridges and vehicles (including railway rolling stock).
A large metals recycler hereabouts regularly receives really good looking car-carriers, even grain cars which are under 10 years old but have been condemned for cracks. Scrap yard personellel, especially the "LABOUNTY" operator can readilly point out these cracks. A "LABOUNTY" is what looks like the king cong of metal knibblers mounted on a large hydraulic excavator---it can chew up a railway car in about 20 minutes. These are the primary machines involved in cleaning up derailments.
it's like watching a mechanical T-rex feeding
