On Tuesday, the United States Navy announced that it had accepted delivery of its second Zumwalt class stealth destroyer, slated to become the USS Michael Monsoor once it has been commissioned.

Once expected to become the new workhorse platform of the U.S. Navy, the Monsoor is the second of only three Zumwalt class destroyers the branch will take receipt of — a sharp decline from the initial order of 32 ships. The first vessel, also the class’ namesake, Zumwalt, was delivered in May of 2016.

The Monsoor hasn’t truly seen the end of its construction phase, however, as the destroyer will still need to have its combat systems installed — a process the Navy anticipates can be completed within the coming months, though officially, the Monsoor isn’t expected to be fully operational until sometime in 2020. The suite of combat systems yet to be installed include weapons platforms, sensors, and the ship’s communication suite.

“Delivery of DDG-1001 [Michael Monsoor] marks the culmination of years of dedication and hard work from our Navy and industry team,” said Capt. Kevin Smith, the program manager for DDG-1000, in a statement. “We have incorporated many lessons learned from DDG 1000 [Zumwalt] and are proud of the end result. DDG 1001 will be a tremendous asset to the Navy.”
