While these might sound like underwater adversaries, they’re actually allies working together to train and test undersea warfare capabilities. Their partnership through the provides each country with opportunities to train their crews and test capabilities while helping their partner nations do the same.
“DESI provides training opportunities against the real world threat – a modern, quiet, diesel-electric
“We don’t have enough of our own subs to train these battle groups. Working with submarines from other countries helps us fill a void for ASW training,” said Rick Current, deputy director for training, tactical weapons and tactical development for Commander Naval Submarine Forces. “Each country’s participation in this program is a contribution to the coalition effort.”
The DESI program has predominately concentrated on partnerships with South American countries operating submarines. These conventional boats comprise nearly 15 percent of the 224 submarines operated in the free world today by 27 different countries. Established in 2001, the program has engaged several navies operating conventional diesel-electric
In the past, battle group training was done in preparation for upcoming deployments by pitting groups of U.S. ships against each other in a series of simulations. That approach provided opportunities for commanders to practice tactics in a variety of combat scenarios. In the post-Cold War environment, however, today’s threat is more likely to come from a modern, quiet diesel-electric
