Since its ascendency to the premier maritime power, the US Navy - especially in the area of undersea warfare - has been at the leading edge of using technology to get a military edge.

During the Cold War, significant and steady progress in the first two steps of the kill chain against submarines, location and tracking, made the prospect of engaging superior numbers of Soviet submarine forces manageable.

We continue that tradition today, but to keep ahead of growing challenges, we have test. Build a little, test a little, learn a lot will stop dead in its tracks without testing in the real world. Computer simulation is only so good.

When it comes to submarines especially, you have to get in the water with them.

Knowing our technological track record an operating a generation or two ahead of some potential adversaries - are there ways they can negate our edge - or at least buy time while they catch up?

Are we vulnerable to potential challengers using national and international law against us? Undersea Lawfare?

Our guests for the full hour to discuss will be Rear Admiral J. Michael "Carlos" Johnson, USN (Ret.) and Captain Michael T. Palmer, USN.

As a stepping off point, we will be using their article in the latest Naval War College Review; UNDERSEA LAWFARE - Can the US Navy Fall Victim to This Asymmetrical Warfare Threat?

RADM Johnson retired after 33 years of service as a naval aviator that included combat in Vietnam, Libya, the Balkans, and the Persian Gulf. He commanded the John F. Kennedy Battle Group, CVW-8, and VFA-86. Ashore he served on the staffs of the CNO as Director of Aviation Plans and Requirements) and the J3 of EUCOM.

Captain Palmer is an active-duty JAG and an adjunct assistant professor at ODU. Her has served as environmental counsel to the CNO; U.S. Fleet Forces Command; and Commander, Navy Region Mid-Atlantic.
