After losing half a dozen survey ships to the aggressive alien species called Yaga Central Command decided to launch a big ships expansion program. At that time the Red Space Navy had only 3 6kt frigates which were obsolete at that point and 36 fighters for home defense. Utilizing the newest armor, armament and propulsion technologies 3 new class of destroyers were designed and a new much more powerful missile.
(Quick side note: I am playing with 50% race research rate. Improved nuclear pulse engines.)
The first new destroyer class was the P-1121 Vigilant. P-1121 means Project 1 (escort) 12 (12kt displacement) 1 (First of this arrangement). The Vigilant is equipped with the biggest and best active sensor suit the Union has to offer. With some additional passive sensors but these were legacy equipment from an older exploration frigate. The idea was that these destroyers will be the fleet eyes but not unarmed and certainly not unarmored. As these ships will have the best sensors in the fleet it was necessary to heavily armor them because an enemy fleet will probably focus it's fire on them. Also she is equipped with AK-102 10cm railguns for point defense and two particle beams for long range engagements. After the first and second battle of Karl Marx it became apparent that the main long range armament was insufficient because the Yaga had a more powerful albeit same range version of it and their ships armor was thick enough to resist multiple hits from it. A quick stopgap solution was needed. Fortunately new capacitor tech was only within months reach. After a year and a half all ships received the "P" upgrade package. (P= Particle) The new particle beam has the same range and strength but 10sec reload time instead of 15. Uniquely in this ships alone was necessary to change reactors too to a more boosted one as the class had very minimal power reserve . In the 3rd battle of Karl Marx (which was more of a minor skirmish) these new guns devastated the enemy formation.
Currently the RSN has 2 units of the Vigilant class and 2 more under production. One for each squadron: SUR Vigilant, SUR Observant and under production are: SUR Alert and SUR Awake.

The fleet needed long range firepower too which lead to the the development of the P-1122 Leningrad class. The Leningrad has a much weaker but lighter sensor suit and armor compared to the Vigiland but she won't be deployed as a single ship in a fleet shining brightly like the Red Star Monument on the Moon during a clear night on every EM sensor in the system. The point defense system is also weaker by 3 AK-102s but all that space was needed for a huge battery of 40 launchers. Currently the ASM-8-2 Granit is in use but the new Granit-M is on the production line with higher speed but lower range. In the second battle of Karl Marx system 4 of these ships launched 160 missiles managing to destroy two enemy ships and damage all the others breaking their formation apart and slowing half of the enemy fleet down to various speeds.. Without these ships the battle could have been lost. After the battle multiple new units were ordered. The big 23kt enemy ships are hellishly durable and in a future battle the Union will propably need a higher alpha strike.
Standard missile doctrine at the time is to close in inside of AMM-range and fire every missile in a huge coordinated strike. If the enemy ASM/AMM fire is too heavy and this tactic proves to be too dangerous the missiles have some extra range to be fired from a distance.
The Leningrad class also received the P upgrade package.
Currently there are 12 P-1122 in the RSN.

The original program had a third DD class too. The P-1123 Hamburg destroyer escort. These ships main purpose was to defend the fleet against incoming missiles hence the 12 AK-102 railgun but also to provide long range firepower. This is why these ships have the heaviest long range armament so far. The ships proved themselves thoroughly in the second battle of Karl Marx. In which the Yaga fired more than 4000 AMM and ASM at the 1st Destroyer squadron but only a handful AMM penetrated the PD network. Sadly even with this much long range armament the firepower proved to be weak against the bigger enemy combatants requiring multiple dozen hits to seriously injure them. The "P" upgrade package helped but the RSN was not content with the available short range firepower.
Currently 10 is in service and 2 is under construction.

After the second battle of Karl Marx and numerous other skirmishes the particle armament proved useful but not powerful enough. Multiple research project are underway to improve the particle armament but those are very expensive and long projects. The RSN needed something for the immediate future and that how the P-1124 Catapult class was born
Equipped with the newest and biggest AK-201 railgun and the newest 33% longer range AK-103 point defense guns the destroyer has a very strong medium range firepower and thanks to the AK-201 multipurpose nature a strong PD capacity.
One ships was ordered for every (4) DD squadron. They could not prove as of now because the Yaga is unusually inactive in the last few years. There were talks in the fleet to upgrade the rest of the ships PD guns with this new AK-104 but it would provide no extra PD capability so the upgrade is delayed for the time being.
Currently there are 4 P-1124 catapult in service: SUR Escopette SUR Fantassin, SUR Fronde, SUR Glaive

The destroyers are organized currently in 4 squadrons. Each have a Vigilant and Catapult plus 3-3 Leningrad and Hamburg class DD. Currently all of them is stationed on Earth because the colonization efforts are only slowly progressing thanks to the Yaga, lack of good candidates, mineral shortages and the Ghost Fleet of Alpha Centaury.
In a few years I plan to upgrade the ships PD weapons, engines, sensors, EW equipment and possibly even armor in a few wave of upgrades. I am also planning to introduce shields an AMM-s to the fleet possibly even a few carriers.
The bigger cruisers and capital size ships will have 0,3 size launchers as I plan to use the DD-s on the long run as a defensive force and the bigger longer ranged ships as an offensive force. But as of now I have to use the DD-s for both roles that is why I gave them almost three years of maintenance life.
