"The Paris-, the Stalwart-, and the Charon-class frigates have been the standard warships in service with the UNSC Navy for the past fifty years, and they have done a fine job. Wouldn't you agree? Wouldn't you agree? But…the United Republic of Earth and Her Colonies is a nation of innovation, and fine…well, that just's not good enough, is it? I present to you…the Remembrance-class guided missile frigate! Faster, tougher, and, admittedly, a little less of a death trap than their older sisters. These SENTINEL frigates will slowly replace their predecessors within the next two decades and surpass them in terms of numbers, but they won't be alone! While the Marathon-class cruiser has proven itself time and time again as being the backbone of the Navy during the Covenant War, there are less than seven dozen still active and it's only a matter of time before they fall to enemy fire. So, our nation's greatest minds, in cooperation with Reyes-McLees Shipbuilding and SinoViet Heavy Machinery are proud to introduce…the Autumn-class cruiser! Now we couldn't have the lead ship present, these newer guided missile cruisers will become the core of the UNSC fleet and defending the URE and its allies within the next decade!"

FADM Arthur Cross discussing the Remembrance-class frigate and mentioning the Autumn-class cruiser during the 2553 Misriah Expo in Vale City, United Coalition of Remnant, c. November 12th, 2553.

Here is a list of every UNSC frigate class. Littoral combat ships have been included as well. I will not be making a list of known guided missile frigates, it will be far too long.

Pre-2553/2554 frigates (FF): Colonial Era/Insurrection Era

•Guardian-class: 2,789 completed (all retired; destroyed by enemy fire, used as target practice, scrapped, or laid up as museum ships; active before, during, and after the Inner Colony Wars)

•Bellerophon-class: 2,655 completed (all retired; destroyed by enemy fire, used as target practice, scrapped, or laid up as museum ships; active before and during the Insurrection)

Pre-2553/2554 frigates: Insurrection Era/The Great War Era; frigate tonnage and role are varied.

•Paris-class (FFH): 918 completed, 61 undergoing trials, 14 under construction (all active or retired; destroyed by enemy fire, used as target practice, scrapped, or laid up as museum ships; active during the Insurrection and The Great War)

•Stalwart-class (FFL/AA): 936 completed, 57 undergoing trials, 25 under construction (all active or retired; destroyed by enemy fire, used as target practice, scrapped, or laid up as museum ships; active during the Insurrection and The Great War)

•Charon-class (FFL/ES): 864 completed, 49 undergoing trials, 72 under construction (all active or retired; destroyed by enemy fire, used as target practice, scrapped, or laid up as museum ships; active during the Insurrection and The Great War)

Post-2553/2554 frigates (FFG, FFS, LCS):

Guided missile frigate (FFG): A concept renewed in the wake of the Great War, it is to replace preexisting frigates by 2586, due to naval casualties during battles with the Covenant's armada during The Great War. UNSC FLEETCOM hopes that by designing an effective replacement rather than redesigning and refitting older ones would help the Navy's frigate fleet recover from the devastating losses that had been suffered during The Great War. The Remembrance-class vessels combines the looks, heavy armor, and firepower of the Paris-class frigate, the troop capacity of the Charon-class, and the Stalwart-class' dependable CIWS suite all in one package.

•Remeberance-class (FFG): 473 completed, 15 undergoing trials, 89 under construction, many more planned (first class of guided missile frigates in service)

Stealth frigate (FFS): An idea first tested during the war, it has been seen as a platform to deliver SOF-capable units like ODST companies and SPARTAN teams unnoticed as well as ambushing enemy fleets with their advanced stealth capabilities. Instead of using Stalwart-class hulls, they repurposed incomplete or retired Paris-class frigates, due to Paris-class vessels having a unique toughness that the Stalwart frigates lack. They have a similar armament as their more common sisters: the Remembrance-class frigates, the difference being HORNET mines, and has slightly more armor than the Remembrance-class.

•Midsummer Night-class: 109 completed, 6 undergoing trials, 81 under construction, 95 more planned (first class of stealth frigates in service)

Littoral combat ship (LCS): fast, agile, and tough frigate-sized vessels that are used to flank enemy naval formations that combine speed, heavy firepower and armor into one package that will replace all corvette classes (now referred to as cutters among the various Colonial Guard organizations) by 2569. LCS-class vessels have a small flight of F-41 Broadsword multi-role fighters onboard as well as a small unit from UNSC Marine Aviation present as well.

•Strident-class: 618 completed, 71 undergoing trials, 48 under construction, many more planned (first class of littoral combat ship in service)

I am introducing something called the GHOST SHIP initiative (now inactive with the end of the Great War), where new frigates receive the same hull number and name as previously destroyed ones, with the hope that the Covenant will fear them. The Covenant's nickname for these ships is Grey Spirits. Remembrance-class frigates are guided missile frigates introduced in late-2555 and early-2556 that will replace all present frigates in service. The lead ship is the UNSC Remembrance, named after a Paris-class heavy frigate that sacrificed itself to protect a group of evacuation ships during the Battle of Miridem.

Remembrance-class vessels are the first multi-role frigates in service with the UNSC since the long-retired Bellerophon-class, combining the heavy firepower and armor of the Paris-class with the troop capacity and dedicated Naval/Marine Air Group of the Charon-class, and the dependable CIWS of the Stalwart-class. UNSC Fleet Command plans to acquire at least, 3,716 Remembrance-class frigates by 2586. By the end of the 26th Century, over 23,000 were in service with human "Black-Water" Navies all over the Milky Way.

These frigates are armed with a single MAC, 8 M2551 Onager Mini-MACs, 12 dual-mounted naval gun turrets that double as point defense guns, 30 quad-mounted railgun turrets, 40 VLS pods (each one capable of launching Archer, Howler or Rapier missiles), 800 anti-aircraft missile cells, a dependable CIWS suite, 1 tube for Shiva nuclear missiles, 3 tubes for Hyperion ISBMs, and 24 tubes for Harpoon anti-ship nuclear missiles. It's hull is made up of a 60cm Titanium-A3 battle-plate, a plasma-refractive coating, and a Acheron Security/Cross Interstellar Dynamic Energy Shielding (frigate-grade) system.

The Remembrance-class frigate was inspired by something similar I found Halo Fanon and belongs to owner and him (or her) alone.

Notable Midsummer Night-class stealth frigates:

*UNSC Midsummer Night (FFS-01)

*UNSC Mother of Invention (FFS-09)

*UNSC Homeward Bound (FFS-26)

*UNSC Nightcrawler (FFS-43)

*UNSC Jolly Roger (FFS-59)

*UNSC Hydra (FFS-85)

*UNSC Outer Shadow (FFS-87)
