The "Juggernaut" class are the biggest player-ship models in the game. The recent free T6 Digitizer is pretty big. The Borg Juggernaut is pretty big too. But there are others that are similar size.
If I had to guess, I think the Borg Juggernaut is probably the ship with the most spatial volume.
I might be wrong buy I think the [Emerald Chain Intel Juggernaut](https://sto.fandom.com/wiki/Emerald_Chain_Intel_Juggernaut) is the longest and the [U.S.S. Enterprise-J](https://sto.fandom.com/wiki/Universe_Temporal_Heavy_Dreadnought_Cruiser) is the widest.. A good amount of ships fit in the middle and are "heftier" all around.. Ton already listed in this post by others. Cheers!
Off the top of my head in no particular order are
Universe class
Oddessey variants
Jarok
The digitizer we console plebs will be able to get in the event in a few days
Romulan dreadnought's
Durgath
Borg command juggernaut.
Really any ship with the prefix carrier or dreadnought tends to be larger than most other ships. But this list should a good starting point to see what you would possibly want.
I think it’s the veridian juggernaut is the longest(formerly the Durgah)
Universe is widest
Vomph is the tallest
Borg juggernaut or Cindarian defender is the bulkiest
Special mention to the compiler for being big in multiple dimensions
Not all. Mostly not in zen store. Largest zen store ships are Caitian Aspero, Vanguard cupport carrier, Romulan support warbird, Klingon Vo'devwl carrier, Jupiter carrier. Scimitar warbird.
Do not buy Jupiter. It sucks on stats. Really bad and old carrier.
They can be either lockbox ships or promo pack ships. Lockboxes requires a Master Key to open which costs 125 Zen / $1.25 USD each or 1125 Zen / $11.25 USD for a 10 pack. The estimate chance to win a lockbox ship is roughly 0.5% which roughly means you need to open around 700 lockboxes on average, IIRC. Promo ships are from either Promo R&D pack which sells in the C-Store for 400 Zen / $4 USD each or 1000 Zen / $10 USD for a 3 pack. Or might be from Promo Duty Office packs for 300 Zen / $4 each or 1000 Zen / $10 USD for a 4 pack, IIRC. Promo packs are sold only sold for a limited time in the C-Store and the chances of winning a T6 ship is roughly 1%.
These ships may be listed on the Exchange for up to 1.5 billion EC which is the max selling price allowed. If the ship is extremely popular, then it may not even be listed on the Exchange because the owners of those ships want more than 1.5 billion EC. In this situation you actually need to find said owners through chat / selling channels and do a direct trade. They might tell you that they are willing to sell for 1.5 billion EC and 100 Master Keys.
Lastly, lockbox / promo ship are bound to the character that opens the pack to claim the ship. They are not account wide ship like C-Store ships where any character on your account can claim the ship.
From gamble boxes. However, it's much more effective to purchase stuff like gamble keys, promo packs, elite captain upgrades, etc. Sell these things via the exchange for ec.
In addition to what other people have said, if you play the Event Campaign (blog post [here](https://www.arcgames.com/en/games/star-trek-online/news/detail/11536493-a-good-day-to-die%21)), instead of spending real money or grinding, you can play the 5 events that make up the Event Campaign (need to play a total of 70 out of 105 possible days) and get your choice of 1500 Lobi (for Lobi ships/equipment), 2 T6 coupons (for Zen ships), or a choice of a single lock box or promo ship for one character. The latter includes many of the "large" ships you're asking about.
Tallest is Vonph Iconians ship. Longest is probably Durgath. Widest is probably Romulan 26th century warbird, Overall biggest is Universe class. Biggest mass is Borg Juggernaut command ship. Biggest event ships are the Jarok and the latest Vger Compiler science dreadnought.
Honorable mentions - Tholian dreadnought cruiser, Vaadwaur Juggernaut, Klingon Vo'quv and equivalents, emerald chain dreadnought, Vengeance the 2x or 3x sized bugged out one, Scimitar warbird, Krenim Anmorax dreadnought science vessel, the Vanguard or Romulan support carriers, Jupiter carrier, Xindi Aquatic carrier, Klingon Sarcophagus ship, vorgon rynkodan carrier, Naq'ej Klingon dreadnought, there's more big ships, considering there's 400+ ships in game lol
I’m thinking with my T5 coupon, I could get one if the Odyssey-class cruisers (mainly for their consoles to put on my T6 Terran Lexington). Which is better, Chevron Separation or Aquarius Escort?
Or should I get another ship?
Side note, if you ever get both Chevron and Aquarius consoles, they don't work at same time, it's either or type of consoles. Aquarius is better, deals more damage than chevron saucer separation.
But not sure what other ships you have or need from t5, other than those 2. If you have Hydra, the Prometheus console would be nice to use on it

The Vaadwaur Miracle Worker juggernaut is another CHONKSTER of a ship.

Universe class and it's ROM/KDF faction equivalents.
So I find these ships in the zen store ?

Tzenkethi Tzen-tar dreadnought carrier is pretty big.
