Spearhawk is a lightly armed colonial freighter, constructed in 2901 as part of a massive colonial exodus to a newly terraformed planet in a system 6000 LY away. (She was one of thousands carried inside the collosal worldship Juno). She is 300 metres long and 60 metres wide. Her shape is mostly cylindrical, but with smooth, muscular bumps on her chromelike surface. Her prow end tapers to a fine point. She has a mass of 100,000 tons.
She is made of a complex artificial substance that is mostly carbon based. (It consists of quite a few light elements that may be susceptible to phaser chain reactions). Her 30cm reflective hull (when not shielded) can deflect light, heat and radiation to a certain extent. She finally meets her "maker" when 12 incredibly powerful dragons decide to make finish her off after her crashlanding. Their fiery exhalations average about 40 gigajoules per dragon, tens of thousands of degrees kelvin, with each dragon exhaling every 10 seconds (please don't ask me about their biology). The firestreams penetrate her hull, tearing through wall after wall. Corridors gush like the insides of flame-throwers. It takes roughly 2 minutes for Spearhawk to explode, but the dragons were simply accelerating the inevitible, for Spearhawk's quantum reactor was set to explode within 5 minutes (yes, the old "exploding reactor" thing, but it's all for the plot - and besides, I'll explain more later).
The crashlanding in question (due to some very convoluted circumstances) has her skidding on her belly into a granite wall at a speed of 150 m/s. Her nose penetrates 60 m into the wall, but that 60 m is then rapidly crushed accordion-like into 30 m.
Her hull also has the ability to "heal" itself. This is due to the billions of sensors, nanobots and "nerves" running through it. (No, this is not your usual "organic technology", this is an example of solid engineering with the complexity of organic life). A critical rend in the hull can be "stretched" closed within seconds.
Her multi-faceted energy shield, at full power, can deflect a maximum of 4 * (10^17) joules at one time - about 100 megatons. This applies to both electromagnetic radiation and kinetic energy. The shield is an extremely fine, massless mesh. The only things that could filter through the mesh without breaking it are gravitons and the psionic influence of truly godlike beings that can use higher dimensions as a medium.
Ideally, she can maintain this power level for 1000 years. Please excuse me, I don't have a calculator with me right now, but that's how much energy her quantum reactor can use within its lifetime. It is a limited means of tapping "zero point energy" - while the energy source itself is vast, the structure of the reactor can only handle so much energy without expensive refits (entropy, wear-and-tear still apply in the 30th century, only the scale has changed).
Spearhawk is not a warship in the strictest sense, otherwise she would have energy weapons in the megaton range. Instead, she has two medium cannons on the port and starboard. Each can fire 2 terawatt gamma-ray bursts twice per second, with a maximum range of 300,000 km. The cannons are light and maneuverable (not the case with stronger cannons), able to make a 150 degree turn in half a second. Their power and beam thickness is easily adjustable, and can be primed for either deep penetration of widespread destruction. Although useless against similarly sized warships, they come in quite handy against small fighters, battle droids, ground vehicles and troops with personal shields. They are also ideal for destroying large, unshielded, ground-based targets while causing minimal colateral damage.
The 2-terawatt gamma ray lasers can maintain continuous full-power beams for up to 30 seconds. Any longer could seriously damage the cannons themselves. Microscopic openings open up in the AI-contolled sheild for the finer beams - risky portals are needed for the broad beams.

!!! This is from my personnal space opera, Sky Ocean, set in 3 different era : 24th century ( the Independence war, in the game it is in the 23rd ), 28th century ( War of Relics ), 29th ( Great War )... No I don't think anything in that universe come close to my Olympus-class : heavy battlecruisers are about 1 km max and have about 10 guns pods...
