Submarine Questions of the Week with ANSWERS 

1- Is the U.S. submarine identification correct? ANS: No, USS Providence is SSN-719, not SSN-716 as the French publication stated.  SSN 716 was the USS Salt Lake City, which has been decommissioned since 2006.

2- Is the sub's given homeport coast correct? ANS: Yes, although the article was imprecise ("based on the east coast of the United States").  As of 2014, Providence is assigned once again to Submarine Development Squadron 12 and home-ported at US Naval Submarine Base New London, Groton, CT.

3- When else was the sub USS Providence in Toulon? ANS: USS Providence was in the port of Toulon, France, from July 13-19, 1990, and made later visits including February 11, 1995, August 5, 1998, May 11, 2001.  reference

4- On what mission was USS Providence at the time of its earlier visit? ANS: On 19 March 2011, the submarine launched Tomahawk cruise missiles at Libyan air defenses in Operation Odyssey Dawn.  

5- With what special type of missiles was USS Providence armed during its earlier visit? ANS:  Most notably disclosed was "USS Providence, a submarine also armed with TLAMs, and a range of anti-radiation missiles, are expected to be called into action during this phase of the operation, shortly before the RAF goes in."

6- The purpose of the special missiles is what? ANS:  Anti-radiation missiles (ARM) are designed to detect and destroy the source of certain enemy radio emissions to degrade the enemy's anti-aircraft defenses in early stages of conflict. The anti-radiation effort is made to reduce friendly aircraft losses. Additionally, anti-radiation missiles can quickly neutralize unexpected surface-to-air missile (SAM) sites during air raids. Hence, in Odyssey Dawn", shortly before and while "the RAF goes in."

7- Why would USS Providence return to the French port of Toulon?  Answer "Unknown", as stated when question 7 was originally posed.  Submarines are stealthy platforms that may perform covert missions rarely made public, unless such disclosure serves a higher national purpose.  Example.

SPECIAL Submarine NOTE

USS Providence (SSN-719) has received three Armed Forces Expeditionary Medals, four Navy Expeditionary Medals, six Meritorious Unit Commendations, four Navy Unit Commendations, six Battle "E" awards, and the Global War on Terrorism Expeditionary Medal.

Submarine Questions of the Week: 29 SEP 2015

The answer to one of this week's submarine questions will likely be unknown for an unknown period of time (up to thirty years, or longer in a few cases, according to published submarine history).

Background [translated from French language] 

An American nuclear attack submarine (SNA) made a stop at the naval base of Toulon from 22 to 26 September. This is the Providence SSN-716, based on the east coast of the United States. Presumably for security reasons, [there has been no enlightenment from the crew]. The maritime prefecture of Toulon terms the stopover "routine".

USS Providence Credited with Submarine History

Background
In 2008, USS Providence commemorated the 50th anniversary of submarine history, the polar transit by USS Nautilus (SSN 571) in 1958, by breaking through the ice at the North Pole in the Arctic Ocean, while en route to the U.S. 7th Fleet's AoR.

Now
Congratulations are in order for the captain, crew, and the dozen or so 'riders' on USS Providence (SSN-719).  The oldest LOS ANGELES class sub of the 30 (active) fitted with 12 vertical launch tubes for Tomahawk cruise missiles,  USS Providence becomes the first sub to successfully luanch a drone while submerged.
 
The Navy announced Dec 5th that in a recent feat developed over six years,  an XFC UAS-eXperimental drone was recently launched using a similar methodology to how the Navy deploys Tomahawk cruise missiles. 

The test launch was followed by what the Navy says was a successful, "several hour" flight. The XFC itself can last for more than six hours on fuel cells, and be launched from something as small as a pickup truck when on land, the Navy says.

Once deployed from the TLC, the Sea Robin launch vehicle with integrated XFC rose to the ocean surface where it appeared as a spar buoy. Upon command of Providence Commanding Officer, the XFC then vertically launched from Sea Robin and flew a successful several hour mission demonstrating live video capabilities streamed back to Providence, surface support vessels and Norfolk before landing at the Naval Sea Systems Command Atlantic Undersea Test and Evaluation Center (AUTEC), Andros, Bahamas. source

The Sea Robin launch system was designed to fit within an empty Tomahawk launch canister (TLC) used for launching Tomahawk cruise missiles already familiar to submarine sailors. source

The timing of the announcement two days before Dec 7th (Pearl Harbor Day) may have been designed to 'throw water on' or delay anticipated announcements of rather superficial drone/submarine progress by Iran, Russia, China, and even North Korea.

As usual, the future will let us know the exact nature of such announcement(s).  Stand by.
