Word on the street is that some of the higher-ups have been talking about splitting the submarine officer path into two separate tracks: SSN/SSGN and SSBN. The idea seems to be that someone taking command of one of America's most important national security assets should have the maximum possible experience operating said asset before becoming Captain. The addition of female officers to the mix adds another issue, since they would likely choose the SSBN path (with SSNs unavailable to them for the foreseeable future) and they'd lose the SSGN platform.
Another initiative, more highly publicized, has been getting the input of younger officers and enlisted men into the design of the submarine control system interfaces through the TANG ("Tactical Advancement for the Next Generation) program. Here's a video about the program:
What do you think about these two new initiatives?
