ANSWERS: Submarine Q.O.T.W. - 28 OCT 2015

Background

There was no general theme to last week's submarine questions. Rather, we selected a variety of surprising tidbits we found interesting.  The mystery photo underlying Question 7 is  found in the original post.

Submarine Questions of the Week with ANSWERS

1 - In "the early 21st century" what typical chain of command (grade) connected with commissioned submarines reverted back to what it had been in the early years of nuclear propulsion ?   ANS: Commanding officers of SSBN crews reverted to O-5s (navy Commanders) versus O-6s (navy Captains) as had largely been routine in the 1960s. 
"In the submarine community, a captain typically commanded a ballistic-missile submarine (SSBN) until the early 21st century when the requisite rank for the position was downgraded to that of a commander. "
2 - With whose navies are "HMS" and "HMJ" associated ?  ANS (HMS): Since 1789, HMS is the British Royal Navy's prefix standing for "His/Her Majesty's Ship".  Within the Swedish and Saudi navies, HMS similarly denotes "Hans/Hennes Majestats Skepp" and "His Magesty's Ship", respectively.  ANS (HMJ): "HMJ" is American submariners' nickname for the Ohio-class ballistic-missile submarine USS Henry M. Jackson (SSBN 730).

ANSAfter a year when submarine crews out of Norfolk had 22 "unplanned losses" for mental health reasons, the program cut that number in the following year in 14, according to Capt.
