(Design by Masao Okazaki)
Built to replace the well regarded Conqueror Class, the Dragon was among the most controversial ships of the 22nd century, with a high degree of criticism to the design throughout their working lives. But what prompted this? Well a lot of things, but first we should probably get into why the ships existed.
To start, we must begin with the Conqueror class, a ship also featured in this document. Whilst they were excellent ships by all metrics, they were only such in wartime. The vessels were large, unwieldy and required more crew and fuel than any other ship in the fleet, or any 5 for that matter. This was acceptable during the Kzinti Wars and Romulan War, when their excellent combat capabilities made it a worthwhile trade-off, but in peacetime the ships, with their short range requiring a support tanker wherever they went, were considered utterly useless. In fact for most of their 30 year career they'd been in storage around Io. And, as the Romulans had raised the white flag, peace (and thus the retirement of the Conquerors) was swiftly in order.
The Dragon Class was one of 4 proposals, alongside the Yorktown, Poseidon and Scimitar. Poseidon and Yorktown were both clearly NX-derived vessels, whilst Scimitar amounted to what could be called a streamlined Conqueror. The Dragon, being a product of the Jefferies Design Bureau, was however derived from the Daedalus class design and wore its lineage on display. Poseidon and Yorktown both offered a lower production cost compared to Dragon, whilst Scimitar simultaneously offered lower R&D times. However, whilst Dragon was the most unusual design, she was also the one most likely to remain capable for the next 10 years and so was chosen as the design to progress with.
And so we get to the Dragon itself. Clad in finely painted material like the later Daedalus class ships, the ship stood at 260 metres in length, among the longest modern ships ever constructed. Above all else, there was nothing worth complaining about with the weaponry. The ship sported no less than 9 Type 2 Phased Cannons, 8 fore and 1 aft. These were included for the very simple doctrinal reason of aiming to melt the enemy's face off. Backing this up were 4 missile and 2 torpedo launchers, placed primarily in the primary hull. The vessel was also among the very first to sport true deflector shields, rather than the basic navigational deflectors of older ships.
The ships carried an ovoid primary hull, something crews came to call the Burger Section. Notably the ship wasn't exactly a radical departure from older ship designs. With a tubular neck borrowed from the Daedalus class. It had what is now a common design of a secondary hull with two pylons, connected to a pair of respectable nacelles. It was in this configuration that the first Dragon was tested prior to her commissioning… and problems were quickly found.
When pushed past Warp 4.1, the Dragon class as-built had a tendency to flex dramatically. On its first test to full speed the warp nacelles hit a peak of 3 relative to the secondary hull before shearing off the ship entirely, leaving it dead in space. It was this sudden and clear design failing that required immediate correction. A pair of additional pylons were fitted to the nacelles, which resolved any major concerns, but the Dragons were limited to Warp 4.5 at maximum for their entire lives. This was, whilst still faster than the Conqueror class, not exactly Warp 10, and disappointing for a ship expected to cruise at Warp 6.
The problems did not end there. The Phased cannons on their own caused substantial heat buildup. This required its own water cooling system, leaving the Dragon not only dependent on water above all other commodities, but with the resultant steam blasts often throwing the ship off of its target. There was also an incident of an ensign using this flash-boiled water to make a cup of tea, which put them in a coma. The use of simultaneous missile and torpedo launchers also caused logistical problems, and the ship could be left without its only way of engaging an enemy not ahead or behind it due to limited storage space for all 6, something the required water tanks for the phasers didn't help with. Additionally, whilst the flexing had been a major design flaw that had been rectified, it was still a concern throughout the ship's service lives.
Consequently the Dragon class would be neither popular nor built in substantial numbers, with only 7 constructed from 2166 to 2169. The ships would quickly be dispatched to the Neutral Zone to show the flag, intimidate the Romulans and keep them away from the prying eyes of the press. For all their problems however, the Dragons did keep the Romulans at bay, something their defenders will be happy to point out. It has also been said that the reason the Romulans never returned was because Earth had reduced the entire Romulan Navy to about 5 capital ships and a couple of tankers by the end of the war, something likely equally if not more important. Ultimately the ships were somewhat well regarded though, and they did gain a following. Strangely this following was more prominent in the Klingon Empire, who had intelligence on the ship and grew to respect it for its proper Klingon values.
The Dragon Class was subject to a technical assessment in 2192, which revealed unacceptable levels of microfractures in their frames. This prompted their immediate retirement, necessitating the entire fleet to return to Earth under tow for fear of the ship's frames finally giving out. One ship, the USS Ddraig Goch, is preserved to this day at the Fleet Museum's secondary site over Europa, where she remains on display to this day. Overall, despite their several alarming flaws, it's hard to say the Dragons didn't make their mark on the history of Starfleet, even if that was by setting a new low bar for Battleships.
