Let's start small and work our way up.
Cúchulainn-class cruiser 'Gáe Bolga'The Gáe Bolga is the first Intercept Orbit ship I'd built. The ship is named after the Gáe Bolga cannon that it carries. Like the A-10 Thunderbolt "Warthog" and its GAU-8 Avenger gatling gun, the Cúchulainn-class started as a huge weapon and the rest of the ship was built around it. As such, she's not so much a ship as she is a massive gun with engines and a crew.

Scáthach-class cruiser 'Caladbolg'Caladbolg is a smaller frigate not intended for front-line battle, but equipped with advanced long-range sensors and ECM and ECCM capabilities. She works especially well in tandem with Gáe Bolga, sharing targeting data to ensure the mighty Gáe Bolga cannon is used as effectively as possible. Caladbolg carries a pair of ship-to-ship torbedo launchers on the underside of her "wings", but ideally she'll never be in a situation that requires her to use them.

MacCumhaill-class Strike Cruiser ' Fragarach'A real dogfighter of a ship, Fragarach wants to get into the enemy line and cause some damage. Shecarries weapons effective at multiple ranges but only basic armor, her crew being firm adherents to the old maxim "the best defense is a good offense". Swoop in, hit hard, only stick around long enough to confirm the kill, and move on. (Note: it's pronounced "MacCool")

(Heavy cannons)

(Point-defense flak cannons)

(Targeting sensors)

(Ship and crew)
Attack Frigates 'Gáe Buide' and 'Gáe Derg'A pair of well-rounded frigates, fairly unremarkable but reliable. I have the two mounted together as a single "capital ship" due to momentary lack of bases.

If playing Dungeons & Dragons has taught me one thing, it's that you should probably not trust someone who introduces themselves with the phrase "GREETINGS FELLOW MORTALS IT IS I."
