Submarine Mystery Questions of the Week

One of the primary obstacles to properly recording history has been the need to maintain national secrets. M.E. acknowledges military secrets are vital to national security and safeguarding them remains an absolute necessity.

M.E will not provide the answer to Question 5, although I seriously doubt the answer I found easily is still secret. .....................................................................................................

The cutaway photo may not be familiar to every submariner. While your guess will have basic validity based on shape alone, proper identification requires more specificity...

Mystery Questions:

1- Name the related submarine class?

2- What is the 3-letter acronym of the unit shown?

3- What was the name (one word) of the system featured in this cutaway photo?

Bonus Question:

4- Where was this cutaway displayed when photographed?

........................................................................

Self Question:

5- In particular, what and where was the primary target the system named in Question 3 was designed to overcome? (You will have to find this answer yourself).

No clue? Answers to Questions 1-4 will be given Friday.

Submarines are always silent and strange, and some of us obviously did not have a need to know such things.
