Silent Force Exercise SIFOREX
Silent Forces Exercises (SIFOREX) was created to provide the Navy with necessary ASW training specifically for diesel submarines.
The first-ever Silent Force Exercise (SIFOREX) was conducted July 20-27, 2001 in the South Eastern Pacific Ocean with tremendous success. Hosted by the Peruvian Navy, SIFOREX was designed as an undersea warfare exercise and included three Peruvian Diesel Submarines, two Peruvian Lupo-class frigates and the U.S. Guided Missile Cruiser USS Ticonderoga (CV 47) and Guided Missile Frigate USS Rodney M. Davis (FFG 60).
SIFOREX was the first time U.S. ships have operated exclusively with Peruvian submarines exchanging engagement theories and testing tactics and Technology. This type of undersea training in a littoral environment is very rare and provides a significant opportunity for U.S. Cruisers, Destroyers and Frigates to train in detecting and engaging undersea targets.
USS Ronald Reagan Carrier Strike Group (CSG) completed SIFOREX 05 July 2004 after four days of Anti-Submarine Warfare (ASW) tactics with the Peruvian Navy. USS Ronald Reagan (CVN 76) is in the midst of Summer Pulse '04, the simultaneous deployment of seven carrier strike groups demonstrating their ability to execute the Navy's Fleet Response Plan. Ronald Reagan CSG is the first group to foster a relationship with Peru through SIFOREX. The Peruvian Navy was chosen for the exercise based on their expert use of diesel subs and their reputation as the best submariners in South America.
During the exercise, Ronald Reagan CSG used several different ASW tactics to locate Peruvian subs. SH-60B Seahawks were used to detect the magnetic signature a submarine gives off. Technology also exists for spotting periscopes and detecting electronic emissions should an enemy submarine choose to use its radar. The entire CSG provided support tracking and spoting submarine movement. In this exercise, Ronald Reagan practiced its evasive maneuvers similar to those used by the Brazilian navy and conducted flight operations during a period of submarine threat. That was very important. The Peruvian navy provided more submarines, training, personnel and equipment for the exercise than was originally expected. They provided us with four submarines, which was unheard of.
