Submarine QOTW, Adm's Quote of the Month, & Panama Canal

Background



 (October 2008)

"China’s Control of the Panama Canal Revisited"
...[I]n the event of a serious military conflict with the United States, such as one over Taiwan, it would be highly possible for Beijing to use Hutchison Whampoa to effectively interrupt U.S. intervention. As former Secretary of Defense Casper Weinberger puts it, Hutchison Whampoa’s control of the canal is a national security threat because “The Company would not be able to survive if they don’t do something the Chinese government tells them to.”[ii] Admiral Moore, a former chairman of the Joint Chiefs of Staff, claims that in case of military conflict in the Pacific, a large number of logistic ships need uninterrupted access to the canal to support deployed forces.[iii] If the use of the canal were denied, those ships would need to travel an extra 9,000 miles around South America and would not be able to sustain combat effectiveness in the Pacific.[iv]  - Yojiro Konno with Nancy Menges.

(June 2016)

"The New Panama Canal: A Risky Bet"  - New York Times, June 22, 2016, WALT BOGDANICH, JACQUELINE WILLIAMS and ANA GRACIELA MÉNDEZ   
Last summer, water began gushing through concrete that was supposed to last 100 years but could not make it to the first ship. The Hill analysts had warned that the consortium’s budget for concrete was 71 percent smaller than that of the next lowest bidder. The budget also allotted roughly 25 percent less for steel to reinforce that concrete. ...

A native Panamanian who graduated from the United States Merchant Marine Academy, Mr. de la Guardia [chief of the tugboat captains’ union] has spent 20 years running tugboats in the canal. “We think it’s going to be a real mess,” he said. “I think something awful is going to happen.”
His concern stems from the canal authority’s decision to abandon [canal-side, electric] locomotives to guide the ships. Tugboats will now push and pull vessels that are more than three football fields long and stacked with up to 13,000 containers, nearly three times as much as the old, smaller ships. Tugboat captains fear that their boats will be overmatched.

(December 2016)

In testimony on Thursday before the House Armed Services Committee's subcommittee on oversight and investigations, Naval Surface Forces Commander Vice Adm. Thomas Rowden revealed that the most recent casualty, damage to the USS Montgomery when it transited southward through the Panama Canal, was at least in part due to failure on the part of canal engineers not to follow the Navy's instructions on how to guide it through the narrow passage.

The Oct. 29 mishap was the second time an Independence-class LCS, with its wider trimaran design, had been damaged passing through the canal. The USS Coronado had also required repairs after a canal transit in early 2014.

"When we took the first ship through and there was some damage associated with it, we sent a team down to the Panama Canal to talk about how we needed to take these ships through the canal," Rowden said. 
*********
Had the good admiral forgotten there had also been this Panama Canal casualty:
"The US Navy's newest destroyer broke down while transiting the Panama Canal, colliding with the Canal lock walls and forcing the $4 billion dollar ship to resort to a tow from a tugboat. The USS Zumwalt was towed to a former U.S. naval station in Panama where it will undergo emergency repairs. This is just months after a similar incident in September."

Which brings us to our...

Quotation of the Month

"Unfortunately with the most recent transit, that was not executed. We've gone back to them and we're going to get it squared away in the future, but we know how to get the ships through the canal safely and if we we execute the procedures as we outlined them, we won't have any problems with that in the future."  - Naval Surface Forces Commander Vice Adm. Thomas Rowden,  Military.com, Dec 09, 2016, "New Details Emerge on Littoral Combat Ship Breakdowns" by Hope Hodge Seck

Answers to Sub Mystery Questions from 19 SEP 2014

Background for questions is found at original posting here.

 ANSWERS - Sub Mystery Q.O.T.W.

Questions
1 - There is a very compelling reason that should have discouraged Taiwan from buying 8 US-made diesel subs; what is it?  ANS:   Bids from seven domestic and foreign companies were received, the FMS [foreign military sales] program was evaluated by the U.S. Navy to cost $10.5 billion, a price tag that led to boycotts of the FMS by the Chinese Nationalist Party (KMT) and the People First Party (PFP) in Taiwan.  Also, a US Council on Foreign Relations commentary said any sale of subs to Taiwan would be too costly and that they are not an effective defensive capability


2 - There is a also a compelling historical reason that should prevent even an Obama administration (with a lawyer in charge of our Navy) from signing onto an FMS (foreign military sales) deal with Taiwan; what is that history? ANS: "Taiwanese military officials have an unfortunate history of passing classified military information into the hands of the People’s Liberation Army (PLA),"

Bonus Questions
(Many former submariners experienced the curious wonder of transiting through a canal in a sub.  Unfortunately, a recent canal transit proved more hectic for one submarine.)

3 - Identify the submarine by name. ANS:  Tayrona de Colombia  (S029), a Type 209, HDW (German-built) sub.


4 - Describe the known damageANS:  Propeller required replacement and transmission system inspected.  Consequently, engines were stopped dead in the water (DIW) in canal, a very vulnerable situation for any naval sub. Unlike Russia (and other submarine powers), however, Colombia's navy quickly acknowledged major repairs and revisions of some of its systems. In 2009, however. Russia's diesel sub Alrosa also had a DIW episode, which Russia immediately attempted to cover-up but failed to hide.


5 - Where was the sub towed for repairs? ANS: Cartagena..after the September 7th incident.

Submarine Mystery Questions of the Week - 19 SEP 2014

Background
In April of 2001, then U.S. President George W. Bush decided to help Taiwan acquire 8 diesel electric submarines. There has been little [sic] progress on such sales mainly because the United States no longer produces conventionally powered subs.

Yet, thirteen years later ...
U.S. Navy official confirms discussion of submarine deal with Taiwan
Washington, Sept. 8 (CNA) A top U.S. Navy official said Monday that he has talked to Taiwan about its efforts to acquire submarines from the United States or build submarines on its own, but he declined to give details.

During a discussion on the Asia-Pacific rebalance held by the Carnegie Endowment for International Peace, U.S. Chief of Naval Operations Jonathan Greenert [former commander of USS Honolulu (SSN 718)] acknowledged having a conversation with Taiwanese officials but said he could not reveal any details.

Questions of the Week
1 - There is a very compelling reason that should have discouraged Taiwan from buying 8 US-made diesel subs; what is it?

2 - There is a also a compelling historical reason that should prevent even an Obama administration (with a lawyer in charge of our Navy) from signing onto to an FMS (foreign military sales) deal with Taiwan; what is that history?

The Bonus Questions
Many former submariners experienced the curious wonder of transiting through a canal in a sub. Juan Caruso says his experience doing so in an SSN was like taking a Rolls Royce through a hand-cranked car wash --- very tedious and time-consuming.  Unfortunately, a recent canal transit proved more hectic for one submarine.

3 - Identify the submarine by name. 

4 - Describe the known damage?

5 - Where was the sub towed for repairs?
