U.S., Peru scout out stealthy, diesel submarines in joint Silent Force Exercise

The USS Rodney M. Davis steams in the open sea in this file photo. The frigates Davis and USS Halyburton, along with the cruiser USS Ticonderoga, recently completed the Navy's first joint exercise with the Peruvian navy.

The first joint exercise ever held between U.S. surface warships and the Peruvian navy’s diesel submarine fleet wrapped up July 27 with shore leave in Callao, Peru, for sailors from the Aegis cruiser USS Ticonderoga and the guided missile frigates USS Rodney M. Davis and USS Halyburton.

Navy Lt. Corey Barker, spokesman for the Silent Force Exercise (SIFOREX), said the exercise “focused on undersea-warfare training aimed at increasing interoperability and appreciation of each country’s naval forces.”

Sailors arrived at Peru’s main navy base in Callao, near the nation’s capital of Lima on July 27, after their weeklong engagement with three Peruvian diesel submarines and a Lupo-class frigate.

The Ticonderoga, commanded by Cmdr. Glen Sears of Honolulu, Hawaii, was designated as the antisubmarine warfare command ship for the four surface ships in the task group, Barker said.

The Ticonderoga, which is based in Pascagoula, Miss., also served as the flagship for fleet exercise leader Capt. Bob Riche, commander of Destroyer Squadron 23.

The exercise began before sunrise on July 23, as the three U.S. warships and the Peruvian frigate Montero set to sea. But danger lurked directly ahead — the Peruvian submarines were lying in wait at the harbor’s outlet, ready to pounce on the exiting ships, Barker said.

Thanks to the ships’ sophisticated sub-hunting electronics and the technicians who operate the equipment, the little fleet was able to locate the “enemy” subs and successfully fight their way out of the shallow harbor into the open ocean, Barker said.

“Leaving a port knowing that there are submarines trying to sink us makes my job very tricky,” said Sonar Technician Geographic Second Class Jeremy Admas of Houston, Texas. “But that is what I do: I find subs.”

Admas said his job was made more challenging because of all the acoustic activity generated underwater by the normal operations of the busy commercial harbor, Barker said.

“It was especially difficult to try and pick out the submarines from all of the noise in the harbor,” Admas said.

SIFOREX 2001 was the first time U.S. Navy ships have had the chance to work with the best of Peru’s submarine force. Officers from the two navies “exchanged engagement theories and tested each other’s tactics and technology,” Barker said.

“We do not have many opportunities to engage in training operations with this many diesel submarines specifically focused on undersea and antisubmarine warfare in a littoral environment,” said Cmdr. Jim Vitha, chief staff officer of Destroyer Squadron 23. “SIFOREX was an important exercise to polish our ability to execute and evaluate antisubmarine warfare maneuvers against very skilled Peruvian diesel submarines.”

The U.S. ships’ technicians, in particular, appreciated the opportunity to play war games with high-quality diesel subs, Barker said.

“This is my first time to work so openly with diesel submarines,” Admas said.” Usually, they are very secretive, but the Peruvians taught us how to detect, recognize and identify diesel subs.”

After the initial break-out from port, subsequent days included a fast-moving exercise in which the ships simulated bombing two shore targets — a dummy radar installation and a “navy base” — while two submarines and two fast-attack missile subs tried to prevent the operation, Barker said.

After the exercise was completed, the U.S. sailors enjoyed free time to see the sights of Lima. Some sailors shopped for native Inca handcrafts in the city’s open markets, while others headed to downtown movie theaters to watch “Jurassic Park III” and “Planet of the Apes,” Barker said.

Sonar Technician Geographic Second Class Cameron R. Bennett of Kennewick, Wash., said he enjoyed his tour of local Inca ruins so much that he’s planning to return to Peru on his own.

“I’ll definitely return for a vacation with my girlfriend,” Bennett said.
