“It will be an impressive destroyer that will absolutely launch us into the next generation of ships,” said Stevens, director of ground assembly at Navy shipbuilder Bath Iron Works.

The stakes are high when it comes to a replacement for the backbone of the fleet as the Navy faces a growing threat from China, whose numerical advantage becomes greater each year.

All of that warfighting gear won't come cheap. The average cost of each new vessel, dubbed DDG(X), is projected to be a third more expensive than Burkes, the latest of which cost of about $2.2 billion apiece, according to the Congressional Budget Office.

“Rather than tying the success of DDG(X) to developmental technology, we’re using known, mature technologies on a flexible platform that can be upgraded for decades to come, as the technology of tomorrow is matured and demonstrated,” said Jamie Koehler, a Navy spokesperson.

The Navy originally wanted to replace Burkes with stealthy Zumwalt-class destroyers with electric propulsion, unusual tumblehome hull and angular shape to minimize radar signature. The program was ultimately truncated from 32 ships to three because of the high cost but supporters said the technological leaps could be useful for future ships.

Indeed, the new destroyers will draw on that ship’s electric power plant to energize lasers while using a conventional hull and a radar and weapon system that's similar to what’s currently in use, the Navy said.

The new destroyer will be fitted with lasers and hypersonic missiles.  It appears to be basically upgrading the weapons systems on the new models.
