At the end of September, the Navy decommissioned the USS Simpson (FFG-56), the last Oliver Hazard Perry-class frigate. The 51 Perrys were the most numerous class of U.S. warships built since World War II until the current littoral combat ship (LCS) program, and the retirement of the last Perry suggests that it would be appropriate to compare the two programs. When they were conceived, the Perrys were certainly as controversial as the LCS; they were derided as toothless and pointless, with a particularly ineffective hull sonar. The advent of towed arrays transformed their value for antisubmarine warfare, since with their gas turbine engines they were inherently quiet, compared to their geared-turbine steam predecessors (the Knox class, which was nearly as numerous).
