The B Word
At the risk of diverting this topic off track I think you are missing the point as well. The black box locator is not designed as or for a SAR beacon, it's there to identify and recover the black box. We are long past the SAR phase of his operation!!
No back on topic; it's good to see that the UK's operators can still produce the goods in the ASW arena, even if we don't have our own MPA anymore. If the USN and Boeing were smart they would lend an aircraft to the seedcorn team for Fincastle 14, even if they could only really enter as a guest crew.
