Just learned that POSKY recently released their Boeing P-8A Poseidon model for FS2004. The Poseidon is the Boeing replacement for the aging P-3C fleet based on the popular 737-800 airframe.

POSKY Boeing P-8A

A well armed 737-800 it is!
This is a really exciting release for the flight simulator community. XML code edits can even provide firing missiles for that real video game effect. FSX compatibility is also good, but read the post below before importing to FSX.
