As of Mid-September, the United States Navy numbered 399 ships, the smallest force level since World War II, and we are programmed to drop to about 325 in 2001. During the August-September time frame, on any given day .1bout 50 percent of those ships were underway. Keeping in mind that about 15 percent of the fleet is usually in overhaul or undergoing extended repair, an underway rate of 50 percent is a very high peacetime operational tempo and one that will be very difficult to sustain over a long period.
