Caldari

Caldari frigate designs.

Bantam
In YC114 each major empire faction, having been embroiled in a harrowing, extensive, long-term war, recognized the growing need for support and logistics functionality in their vessels during the kind of protracted interstellar warfare that might otherwise prove exhausting for its participants. In the Caldari State, this led to the redesign and redeployment of the Bantam. The Bantam, a strong and sturdy craft, was originally an extremely effective mining frigate. After its redesign, the Bantam's large structure had to give way for logistics systems that ate up some of its interior room but allowed it to focus extensively on shield support for fellow vessels.
Condor
The Condor is fast and agile. It has limited cargo space so it's not very suitable for trading or mining. It is best used as an assault vessel in a hit-and-run type of operations.
Griffin
The Griffin is much used by the Caldari Navy as a support vessel in combat squadrons, using its impressive array of electronic gadgetry to disrupt the operation of target ships, making them easy prey for traditional combat vessels.
Heron
The Heron has good computer and electronic systems, giving it the option of participating in electronic warfare. But it has relatively poor defenses and limited weaponry, so it's more commonly used for scouting and exploration.
Kestrel
The Kestrel is a heavy missile boat with one of the most sophisticated sensor arrays around. Interestingly enough, it has been used by both the Caldari Navy and several wealthy trade corporations as a cargo-hauling vessel. It is one of few trading vessels with good punching power, making it ideal for solo trade-runs in dangerous areas. The Kestrel was designed so that it could take up to four missile launchers but as a result it can not be equipped with turret weapons nor with mining lasers.
Merlin
The Merlin is the most powerful combat frigate of the Caldari. Its role has evolved through the years, and while its defenses have always remained exceptionally strong for a Caldari vessel, its offensive capabilities have evolved from versatile, jack-of-all-trades attack patterns into focused and deadly gunfire tactics. The Merlin's primary aim is to have its turrets punch holes in opponents' hulls.
