The first fleet of the HDC leaving their own territory and former territory jumped out of hyperspace in another system. During the dangerous jump their long range communications ship got destroyed by some space rocks. The rest of the fleet is doing well so far. The fleet is mainly mad out of war ships. There are 5 Tower class Cruisers. Even though they are outdated, they still are powerful and the main fleet isn't weakened by them missing. the second largest vessels in the fleet are the 2 Swarm class Missile Cruisers. They are very up-to-date and can take on even vessels of similar size without problem, but they are best used for fire support from the second row and are very vulnerable to being flanked. The main direct firepower is provided by the 6 Breaker class Frigates. They combine speed, broadside firepower and a small railgun at the front. In lack of defensive capabilities, the HDC hat to set on firepower, so their most important ship type so far is the Destroyer type. That said, the first class of Destroyers are the 4 Wall class Destroyers. Its of medium size and with 12 big guns its armed to the teeth. The segmented build stile makes it able to ignore the lose of cannons without leading to chain reactions. The 10 Doom class Destroyers are way smaller and have the size and price of a fighter, but the firepower it can provide with its 6 cannons outreaches everything that could be considered a fighter. The only downside: it needs ages to reload its weapons.
These were the warships. Besides the warships, there is also 2 Spy class Sensor ships.
Another important part are the 4 Spike class Minelayers and 1 pulled Railgun. The uses of these are to protect the retreat of the fleet in case they find more hostile civilizations.
