The Navy is set to select a contractor to create the next generation of presidential helicopters. The selection will come five years after the previous contract to build the helicopter was scrapped because of delays and cost overruns. Up for replacement are 11 VH-3D helicopters that date to 1975 and eight VH-60N choppers that joined the fleet in 1989. The helicopters have been upgraded over time, but many feel they are nearing the end of their useful lives and need to be replaced. The Pentagon expects a new fleet of 21 helicopters, possibly a version of the existing S-92, to be ready starting in 2020 at an unspecified cost. Read related article.
