I’ve been wondering about this for a while, and although we cannot access the descriptions of several ships now, I have been able to get some of them from the Wiki.
This is going to take a while and a lot of working through, but I’m hoping that we can find some clues as to what kind of age and availability each ship has.
We’ll start with the Empire - best foot forward and all. ;)wt
Now, the Empire gives me the only concept I feel confident to say absolutely:
Tier 1 ships are over a thousand years old!
The evidence for this? Let’s take a look…
- The Harpy is stated as once being “best ship of the Direktorium”. The Direktorium fell as Earth’s government in the 36th century.
- The next supporting point is the Iron Harpy, a Legion Frigate based upon the Harpy. To quote the official wiki: “The elite of the Imperial Space Navy is undefeated Legion, a large body of troops, created at the dawn of the fleet under the command of the Emperor”. The Legion have thus existed from the dawn of the Empire (or the end of the Direktorium if you prefer), and the Iron Harpy was reported modified slightly by the Legion for their own use. This further reinforces the idea that the Harpy predates the Legion and the Empire.
- The Hercules flavour text states, ‘This fighter has formed the basis of the Army from the moment of Imperial declaration. It has been removed from service, and is used in Army schools.’ This is pretty clear cut - the Hercules was around since when the Empire came to be, which would require it to be over a thousand years old.
This of course suggests that other Tier 1 ships, from Jericho at least, are of a comparable age. Federation ships would obviously be newer since they didn’t come back until the 38th century at the earliest.
The tricky part, from the Empire point of view at least, is that T2, T3 and T4 ships are full of references to them being an active part of the military. For example, Hydra frigates (all variants) are described as being the mainstay part of the army, Cerberus ships are part of “assault vanguards” and T4 are, respectively, cancelled and technically doesn’t exist, “the frigate of the Imperial Guards”, and the frigates charged with defending the Imperial Battleship.
My general theories here are that T2 Empire ships are meant to be the front-line vessels of the second war with Jericho, making them around 400 years old. T3 ships are ‘modern’ vessels; they are starting to get on in years, but are still good enough to function as front line warships in the coming war. T4, finally, are cutting edge vessels; the latest developments that have only just come into use, or else have yet to be put into full scale production.
Not sure how T5 will tie into this though. One theory might be that T5 ships will be created as a direct result of the massive influx of Precursor tech, effectively causing T4 and T5 ships to be developed within a decade of one another, yet have a significant jump in power.
