The Navy’s Problems and Underway Time as a Measure of Availability

USS John S. McCain

The US Naval Institute reports the Navy is acknowledging that they have too often let training slip, particularly among those ships forward deployed to Japan.

The Navy has been largely unable to say no to missions it’s been tasked to do in the Pacific despite not having dedicated training time or keeping up with required certifications, the chief of naval operations said in a Tuesday Senate Armed Services Committee, highlighting the bad confluence of high-demand, low resources and a “can-do attitude” within the service.

SASC Chairman Sen. John McCain (R-Ariz.) said in his opening statement that “the McCain (DDG-56) had expired training certifications in six out of the 10 key warfare mission areas. The Fitzgerald (DDG-62) had expired certifications in all 10 mission areas.”

The Coast Guard certainly has suffered its share of “Can-Do-i-tus”

I suspect much of the Navy’s overworking of their personnel is self-inflicted. Why?–Take a look at how much the Navy is underway as I will explain below.

We have all made those reports that apparently served no purpose; well intentioned reports that should have been limited to a specific period to answer a specific question; programs that are well intentioned but relatively unimportant that just crowd out what should be priority work. Even the Navy’s certification program may be unrealistically onerous. They may not have support, facilities, or funding, particularly those based in Japan, but at least I think they have time if they could get rid of the unnecessary.

How much is the Navy underway?

The USNI also provides a weekly update entitled “USNI News Fleet and Marine Tracker” ( Having looked at the last eleven weeks, less than a third (31%) of the Navy’s 276 “Battle Force” ships (including 58 MSC ships) are underway at any one time ranging from 81 to 90 ships (average 85.9). They do have a bit over a third of their ships are “deployed” (36.5%, 100.6 on average) but only 65.5% of those are underway. Ships that are not “deployed” are only underway 11.7% of the time.

The Coast Guard has historically used 185 days away from homeport criteria as a reasonable upper bound for scheduling ships, but that of course does not translate into mission days. It may include logistic stops, time in other ports, or even maintenance in a shipyard in a city other than the homeport. Congress has asked us to use another metric to measure availability. Perhaps percent of time underway is a good measure. Undoubtably it would be less than 50%, but I suspect we compare favorably with the Navy in percentage of time actually underway. We probably should make an effort to use the same criteria the Navy does.
