Legendary starship

The legendary starship was a high-profile starship type developed by Starfleet in the early 2410s decade. This type of starship was inspired by "hero ships" from pivotal moments before and during Federation history. They were conceived of at the end of 2410. Through Excalbian time travel, this classification was validated at the Battle of Excalbia in early 2411. 

History and specifications
Following a series of wars and crises that saw action for both brand-new starship classes, and refitted "classics" benefitting from a fleet modernisation program, Starfleet provided upgrades to ten existing ship types to bring them up to level with the latest designs. 

Initially, the family of exploration cruisers was upgraded to tier 6 legendary command exploration cruisers, receiving new abilities - including command starship rating - and stats. 

The next line was included the and related tactical escorts. These were upgraded to legendary pilot warships, and enhanced version of pilot escorts. 

Starfleet's initiative proved prophetic. During a Borg crisis at Excalbia in 2411, Captain Va'Kel Shon of the USS Enterprise (NCC-1701-F) let a fleet of Enterprises and other "hero ships" from previous centuries into the Battle of Excalbia to assist a Khitomer Alliance vessel in defending the planet from a Borg Queen and her fleet. 

The ships of Shon's fleet, in order of arrival, were:
 * USS Enterprise (NCC-1701-F)
 * USS Enterprise (NCC-1701-D)
 * USS Enterprise (NCC-1701-E)
 * USS Enterprise (NCC-1701) (, 2260s era)
 * USS Enterprise (NCC-1701) (, 2250s era)
 * USS Enterprise (Kelvin timeline NCC-1701) (, Kelvin timeline)
 * USS Defiant (NX-74205) (II)
 * USS Voyager
 * USS Discovery

Each of which represented a version of a ship class receiving the legendary starship update.
