Design History:
As the 1920s dawned, the state of the Columbian destroyer fleet was becoming a growing concern. Some parts of the Columbian Admiralty (later coined the Battleship Mafia), as well as Congress, had preferred to push out iterations on the old four-stacker hull design, rather than offer a direct competitor to contemporary foreign designs.
This was based on the thesis that destroyers could not bring about a defeat over an enemy battle fleet. The only reliable tool to defend the Columbian shore from hostile capital ship incursions, they argued, was to draw the opposing force into a decisive engagement in the open sea. As torpedoes did not yet have the lethality or range to pose a serious threat to enemy capital ships, they were relegated to the role of torpedo boat hunters; high speed gun platforms forming a defensive screen around the Battle Force. However, since the vast distances from any enemy-held shore meant that destroyers were unlikely to form a major part of a hostile force gunning for Columbian shore targets, destroyers in the view of the Battleship Mafia and Congress were pretty much left without a purpose.
By the early 1920s however, destroyers had grown in capability, especially in the Royal Alantian Navy and the Alantian sphere of influence. Together with the rising threat of submarines, the writing was on the wall that other competing nations would soon begin to field their own large destroyers. Thus, finally, Congress pushed for a revolution in Columbian destroyer design after considerable lobbying from various Admirals. The Battleship Mafia remained stubborn, and eventually Congress had to order the decommissioning of one of Columbia’s oldest two dreadnoughts, East Mariana, to free up treaty tonnage for a new class of destroyers.
Three plans were proposed: One envisioned 16 smaller craft of comparable size to existing destroyers. Another envisioned a small run of very large destroyers based on the RAN’s oceangoing destroyer prototypes such as RNS Sable. However, a middle ground of ten quite large warships would emerge as the most rational choice.
Gun firepower was a design priority, reflected in a, for the time, heavy battery of six five-inch guns in three twin gun houses with partial splinter proofing. Speed was modest for the day at around 35 knots (though some ships would exceed 36 knots on trials). Anti-aircraft armament was a single three inch short barrel AA gun abaft the funnels and a pair of machine guns. ASW armament was considerable for the day, reflecting the Columbian Admiralty’s concerns that submarines might take a considerable toll on the Battle Force.
Early during construction, the ten ordered ships were cut down to nine as it became obvious that the design was growing overweight. The first ship, CFN Hill, would be launched in May of 1927. On trials, her seaboat quality was considered as “barely satisfactory”.
The 1927 New Bethburg Destroyer Convention:
While the first few ships were undergoing sea trials, diplomats from Alantia, Columbia, Ming, Solmonte, Basquerana and Normannia met in New Bethburg to formulate the 1927 Destroyer Convention, one in a series of treaties attempting, largely unsuccessfully, to limit the size and number of warships being built across the world. In this particular case, the Convention dictated that no future destroyer of the signatory nations would exceed the size of the Hill class, which was rounded to 2000 tons ordinary load displacement. An option was provided to build a small series of oversized destroyers to a 3000 ton displacement limit under a penalty.
Other stipulations were also made to provide a rough definition of what constituted a destroyer, however these were not always followed (For example, a destroyer was thus defined as a “warship whose main role is the employment of torpedoes”. This would by some definitions discount the Hill class themselves, as their main role was to be a gunship.) As with all the naval treaties, rules-lawyering and understating displacement figures resulted in an only notional compliance to the treaties across signatory nations.
Operational History:
During the first two years of their service, the ships would be split across various divisions to act as division or squadron flagships due to their larger size. This proved unpopular and was soon rescinded, with the ships forming the 32nd DesRon, 72nd and 73rd DesDivs, initially based out of White Cove Naval Yard on the Columbian west coast.
During the interwar years, the DesRon would be split up, with DesDiv 73 (now 173) heading to the east coast, but by the outbreak of war they were recalled in a hurry.
The west coast ships were heavily engaged during the opening days of the war. Blair was on patrol on the night of September 1st when she encountered the Ming destroyers Banwai and Tsogang, providing distant escort for the troop ships headed for Tunfish Bay. Upon spotting them, she issued a challenge via blinker light. Initially, the Ming vessels identified as Fushani destroyers, but Capt. Henry Baker aboard the Blair was suspicious and ordered to close and illuminate the ships with searchlights, whereupon the Imperial vessels opened fire. Blair was caught off guard at point blank range, with the opening salvo crippling her No1 mount shell handling room and starting a fire forward. Capt. Baker ordered a radio alert to be broadcast and attempted to open the range, but a torpedo impacted Blair amidships and split the vessel in two. Blair’s radio alert did serve to provide some kind of warning however, and bought crucial minutes for the island’s garrisons to prepare.
As the war progressed, the single purpose nature of the ship’s guns, and their small margin for upgrades became a major concern. Many of the ships were relegated to East coast operations or the northern theatre where they could be kept away from carrier aircraft. Nevertheless, Henry would be sunk by air-dropped bombs in 1941, while Clint would sink three years later after hitting a Solmontian mine. This made them one of the most loss-intensive classes of destroyers in the CFN during the conflict by units lost.
Postwar, the ships were regarded as wholly obsolete and, after their Magic Carpet runs, were soon listed for disposal, with the entire class being sold off in 1946 for scrapping.

Aldern in Measure 5 camouflage during the early stages of the war. The mainmast has been cut down to reduce topweight and clear arcs of fire for her AA gunners.
The Hill class was rarely dressed up in the otherwise popular three-colour dazzle patterns. This is Turville wearing Measure 14. Note the early powered director for her 37mm gun. This unit proved to be maintenance-intensive and was later replaced with manually operated ones.
