KROTUS class

The Weytahn Incident prompted the Andorian Imperial Guard to construct the massive Krotus-class carrier ship as a symbol of Andorian power which could match the might of the emerging militarism of the Vulcans. Only two of the carriers were built and were used to service and reinforce Andorian colonies. In addition to serving as command ships for Andorian fleet movements, the Krotus-class carriers were equipped with fighter and recon spacecraft as well as dropships and other infantry equipment for planetside campaigns. The first ship of the class, AIG Krotus, was destroyed by the Romulans at the Battle of Andoria.

KUMARI class

The Kumari-class battlecruiser had a standard crew complement of 86 and was the primary ship-of-the line in the Andorian Imperial Guard. While the Kumaris were equipped with deflector shields, the hull was vulnerable when shields were down because it lacked polarized hull plating. The Kumari-class ships utilized stolen Vulcan technology in their computer operating systems, which made them susceptible to the Romulans' telecapture weaponry.

PHINDA class

The Phinda-class heavy cruiser was the pride of the Tellarite Star Navy, though they were largely ineffective in combat operations during the war due to their vulnerability to the Romulans' remote hijacking device. The Phindas were highly maneuverable, however and were instrumental in destroying an enemy carrier at the Battle of Cheron.

D'KYR class

With the election of Administrator V'Las and increasing tensions along the Andorian border, the Vulcan High Command commissioned the construction of the D'Kyr-class heavy cruiser which ushered in a new age of militarism for the Vulcan Expeditionary Force. The D'Kyr was the pride of the Vulcan space fleet; they were heavily-armed, fast, and protected by state-of-the-art deflector shields. Despite their strength, the D'Kyr was vulnerable to the Romulans' advanced jamming technology.

K class

By the 2150's, there were over 220 ships under contract by the Earth Cargo Service Authority roaming the stars along the Alpha/Beta Quadrant border. The ECS fleet supplied the human colonies, delivered private passengers, seeded the space lanes with communication relays, and traded with alien species like the Orions and the Rigellians. The "K-class" freighter (named after the legendary Kobayashi Maru), could reach a top speed of warp 4.5, making the K's the fastest civilian craft of its era.

ELITE class

By 2155, the shipyards at Alpha and Proxima Centauri were the leading producer of civilian spacecraft in Sector 002. The Elite Observer, a popular civilian ship by Cochrane Industries, was a renowned pleasure craft used to ferry diplomats, scientists, and tourists across the human colonies. After a devastating Romulan assault on the Centauri cluster, the Elites were discontinued and eventually faded into obscurity. One of the rare Elites was personally preserved by Hannah Cochrane and is on display at the Starfleet Museum's Proxima Annex.
