First Frigate
Name: Terror of Tarre/ Tarre’s Terror
Reasoning: Tarre Vizsla was the first and only noted Mandalorian Jedi in Star Wars canon. This reflects Clan Vizsla’s nature, we take in anyone who is willing to work for credits. His last name and membership in the Vizsla Clan of canon is also a connection to our Clan within the Dark Jedi Brotherhood. There are two versions of the name provided, both are meant to have an alliteration like sound. I am ok with either name if chosen but I know some people dislike having apostrophes in ship names so I wanted to cover all my bases.

Frigate with the Clan Fleet upgrade (The Flagship)
Name: Malignant Mythosaur
Reasoning: The Mythosaur was a legends Mandalorian creature that has been brought into canon due to season one of the Mandalorian. While learning to ride a Blurrg the Mando is told by Kuiil the Ughnaught that his ancestors rode the great Mythosaur. Like the Mandalorians of old this is a ship that we will ride into battle. The first part of the name, Malignant, can mean Malevolent. This is a bit of a callback to the great warship of General Grievous, The Malevolence. Like the Malevolence, this ship is the secret weapon of our fleet. We too have the ability to wreck havoc with the systems of enemy ships like The Malevolence’s Ion Cannon Super Weapon but instead of using a projectile we have the Shroud Slicing Computer. Malignant can also refer to something that is virulent and infectious. This is a subtle hint at the nature of the Shroud Slicing Computer. Like a computer virus, it is used to infiltrate the systems of enemy ships and slowly take control away from the enemy.

Galaar - named after a bird of prey native to Mandalore (name is also similarly used for blasters used by various Mandlorian groups in fiction)

Striile - another native predator from Mandalore. It is an intelligent hunting "dog" that is known to be very loyal to its master, and rewarded by being essentially a beloved family-heirloom (as they survive long beyond the normal life span of a Mandalorian)

I would suggest naming them the Kalita and the Tokursh. Both of these were important regions of Mandalore, Kelita being a river valley that was home to the capital city of Keldabe and Tokursh being a region known for its rich deposits of Beskar. Tokursh is apparently orchard in Mando'a, which is rather fitting given how much of the beskar that they undoubtedly pulled from the region. The Kelita river valley was home to many battles and is probably the most mentioned region on the planet. Too bad the Vong had to go and ruin it.
