cruiser per aircraft carrier group to host the group's air warfare commander, a role for which the destroyers do not have sufficient facilities. Flight III Arleigh Burke-class destroyers equipped with the Air and Missile Defense Radar provide enhanced coverage, but putting the radar on standard destroyer hulls does not allow enough room for extra staff and command and control facilities for the air warfare commander. Destroyers can be used tactically for air defense, but they augment cruisers that provide command and control in a carrier group and are primarily used for other missions like defending other fleet units and keeping sea lanes open. Congress opposed the plan on the grounds that it makes it easier for Navy officials to completely retire the ships once out of service. The Navy would have to retire all cruisers from the fleet by 2028 if all are kept in service, while deactivating half and gradually returning them into service could make 11 cruisers last from 2035 to 2045. Replacement of the cruisers was repeatedly delayed by funding due to commitment to the , so work on a new cruiser was expected to begin in the mid-2020s and begin fielding by the mid-2030s. Due to the large overlap in size and capabilities of its guided missile cruisers and destroyers, the Navy eventually coalesced them into a single class of large multi-mission ships with an emphasis on air and missile defense called Large Surface Combatants (LSC); in 2018, the Navy stated that a future LSC would have capabilities of the Flight III Arleigh Burke-class guided-missile destroyers as a starting baseline while having future growth margins and air defense command and control of the Ticonderoga class. Consequently, the short-term replacement for the first decommissioned cruisers is the Flight III Arleigh Burke class starting in the mid-2020s, while the last of the Ticonderoga-class cruisers and Flights I and II of the Arleigh Burke class will be replaced by the DDG(X) program in the early 2030s. The program office was established in June 2021, and design work was contracted starting in February 2022. Despite the designation, the DDG(X) is expected to be considerably larger and at least as capable as the Ticonderoga class. Design The Ticonderoga-class cruiser's design was based on that of the Spruance-class destroyer. The Ticonderoga class introduced a new generation of guided missile warships based on the Aegis phased array radar that is capable of simultaneously
