The USS Yorktown (NCC-98300) was a Block II reconnaissance Yorktown-subclass of the Odyssey-class star cruiser, based off of the first generation Block I/S Odyssey variant with the same name, the NCC-97005.
The Yorktown was the first of its line to be designated as a Block II/S Yorktown-subclass variant of the Odyssey-class, a second generation super-capital command vessel specializing in long-range reconnaissance and scientific survey operations. The ship was an overhaul from the USS Yorktown (NCC-97005), itself a reconnaissance refit of Block I fleet-element Odyssey-class flagships, that was destroyed near San Francisco Fleet Yards in an assault on Earth by Herald ships. In the recovery efforts following the Iconian War ceasefire, Starfleet Command decided that the namesake predecessor's remains were a prime template for extensive refit, stripping down the recovered derelict and improving on its design rather than refurbishing it for active duty. With a Yoyodyne 47B M/ARC warp core, two Keenser/Pegg heavy impulse engines, and two inline flux secondary impulse engines, the vessel was given the highest speed efficiency rating of its time. Equipped with a JAWS active directional sensor array, twelve DYN-90 multi-band linear sensor suites, and four omni-wave sensor matrices, the II/S variant was tuned to be more sensitive than the I/S. It also boasted larger nacelles that were developed to provide redundancy to key field generation systems, and a hull plating that was coated with a duranium/nanomesh exterior, in accordance with sixth-generation Starfleet Corps of Engineers starship construction methods. The II/S had a formidable mass, with a superstructure with a recorded mass of 6,873,200 metric tons and a length, beam, and draught of 1041.5 m, 385.32 m, and 150.84 m, respectively. Its defensive systems included twenty-one Mark XIV phaser arrays, six variable-payload torpedo launchers, and three Yoyodyne 960-B Unified Field Emitter Arrays. An outstanding feature of the II/S subclass, the emitters were capable of harnessing a full spectrum of exotic energies and particles that could, in turn, be channeled as a dampening waveform capable of interfering with isolinear circuitry on a subatomic level in hostile targets, damaging and disabling their systems. The vessel was able to compliment 900 crew at minimum operational requirements, 2100 under optimal deployment,<ref="TTC Jayce's Navy Interstellar></ref> and 2500 at maximum capacity. As a proof-of-concept variant of the Odyssey-class, the NCC-98300 was considered a template for all Block I Odyssey hull refits to Block II sublclasses going forward.
