The USS Cole was not the first US warship to be lifted like this after suffering damage. There is nothign embarasing about transporting a ship this way. If there was no risk involved in sailing them, they would be called "cruise ships" and not "warships". There was nothing embarassing about bringing the USS Cole home after it was attacked by a bunch of nutjobs.

I was thinking it was the sonar absorbing tiles that were damaged and not where the sail meets the pressure hull.
Would it been better for the Cole to have sunk with a much higher loss of life? Your alleged embarrassment is sailing today thanks to being hauled back. While tragic the Cole has been an excellent data mine for damage control and force protection and was a much needed wake up call for the not only the USN but most other Western navies.

There might be a few problems hauling her back on a barge. The nuclear reactor needs seawater cooling, for one thing.
SOP when a collision is imminent is to down all masts. That could be why you don't see a scope up.

It still needs cooling when it's shut down.

The Navy has sent a shipyard crew out from Pearl to work on the Hartford. I guess they hope to jack the sail back into place for the transit home.
Navy Inspects Damaged Ships After Collision
Navy Times, March 23, 2009
Navy engineering teams were at work (including a team from Pearl Harbor repair facility) Monday in Bahrain inspecting the damage to two warships that collided Friday in the Strait of Hormuz, hurting 15 sailors.
The fast-attack submarine Hartford crashed into the underside of the amphibious transport dock New Orleans early Friday morning while both were underway in the narrow waterway that connects the Persian Gulf with the Indian Ocean. Both ships arrived in Bahrain under their own power on Saturday, although Hartford transited on the surface. At the time of its collision it was at or near periscope depth, about 65 feet below the surface, the Navy said.
Navy photographs show severe damage to Hartford’s sail, which cracked on the port side where it joins the ship’s hull, apparently because of the impact and strain from colliding with New Orleans. The photos showed a decided rightward lean to the sail, plus damage to the metal and sensors along the leading edge, and a long scrape along its port side. The ship’s crew sewed together vinyl sheets from the ship’s galley to cover the sensors inside the sail, a Navy spokesman said.
Navy photos did not appear to show any damage to New Orleans above its waterline.
Cmdr. Jane Campbell, spokeswoman for 5th Fleet, had no new information about the ships on Monday other than inspectors were continuing to assess what kind of repairs Hartford and New Orleans will need. She could not say whether the damage New Orleans sustained to its ballast tanks affected its ability to ballast down for well-deck operations.
A Navy press release did say that officials believed the 25,000 gallons of diesel marine fuel that spilled from New Orleans had dissipated; patrol flights over the Strait of Hormuz found the slick had mostly evaporated.
The Navy has released no initial explanation for what could have caused the collision. It’s possible Hartford was trying to hide under New Orleans to disguise its entry into the Persian Gulf, although unless that maneuver was coordinated in advance, New Orleans’ crew may not have known the submarine was there.
The gator has no sonar with which to listen for submarines, said naval analyst Norman Polmar, and even if it did, Hartford is designed to operate quietly and avoid detection. He also said the submarine’s crew members might not have known how close they were to New Orleans if the narrow channel was crowded with surface contacts.

I guess it's too soon to rule out a really sharp turn, or a brutal southerly wind.

Sub rolled 85 degrees after collision
Staff report
Posted : Friday Mar 27, 2009 16:44:05 EDT
Investigators think the attack submarine Hartford rolled 85 degrees after it collided with the amphibious transport dock New Orleans in the Strait of Hormuz on March 20, according to a Navy statement.
The Friday press release from 5th Fleet confirms initial chatter on how violently the two vessels collided, which occurred around 1 a.m. while the submarine was transiting into the Persian Gulf submerged but near the surface. Fifteen Hartford sailors were injured but were able to return to duty.
“Despite the roll, engineering investigations have confirmed the propulsion plant of the submarine was unaffected by this collision,” the statement said. “However, Hartford sustained damage to its sail and periscope, as well as the port bow plane.”
The collision punched a 16-by-18 foot hole in New Orleans’ fuel tank, and two interior ballast tanks were damaged, the statement said.
Both vessels are in Bahrain undergoing repair assessments. At the same time, two investigations are underway: a Judge Advocate General Manual investigation and a safety investigation. The JAGMAN is being led by Capt. Craig Kleint, commodore of the Dock Landing Ship Class Squadron. He is joined by a post-command submarine officer and a three-person legal team.
Both investigations are expected to last 30 days, but that can be extended, the statement said.

The Hartford is making a surface transit back to port. In the photo you can see the repair to the sail.There is a hires photo. Both the skipper and chief of the boat [COB]have been relieved.
