Tactical systems


Phaser Turret arrangement: Three dorsal turrets on the saucer section, one for the forward, starboard and port sides. These turrets are duplicated on the ventral side of the primary saucer. One ventral turret on the primary hull, dead aft covers the aft firing arc. The turret itself is located beneath the aft engineering hull Shuttlebay.

Phaser Turret Type: The Excelsior Class starship is a medium sized vessel, and utilizes the Type VIII turret system. The seven arrays are all type VIII turret emitters. Each array fires a pulsed beam of phaser energy, discharging the phasers at speeds approaching .986c (which works out to about 182,520 miles per second - nearly warp one). The phaser array automatically rotates phaser frequency and attempts to lock onto the frequency and phase of a threat vehicle's shields for shield penetration.

Phaser Array Output: Each phaser array takes its energy directly from the impulse drive and auxiliary fusion generators. Individually, each type VIII turret can discharge approximately 2.75 MW (megawatts).

Phaser Array Range: Maximum effective range is 300,000 kilometers.
Primary purpose: Assault
Secondary purpose: Defense/anti-spacecraft/anti-fighter


Arrangement: Two fixed-focus torpedo launchers, located just above the main deflector dish in the neck of the vessel. A third launcher is set to fire dead aft and is located on the rear of the engineering hull just below the aft shuttlebay. These launchers are the second generation of automated, high-speed launcher originally found on the Constitution-Refit Class starships. Since the launch of the Excelsior Class, however, the vessel has had continuous upgrades to keep the vessel up to date with modern Torpedo Weapon technology. The last upgrade for the Excelsior Class saw the installation of torpedo launchers designed and deployed for use with the Akira class. These launchers are highly automated and can fire a maximum salvo of 5 torpedoes per launcher from the forward launchers and 3 torpedoes from the aft launcher.

Type: Mark XXV photon torpedo, capable of pattern firing (sierra, etc.) as well as independent launch. Independent targeting once launched from the ship, detonation on contact unless otherwise directed by the Chief Tactical Officer.

Payload: Excelsior Class starships can carry a maximum of 120 torpedoes.
Range: Maximum effective range is 3,000,000 kilometers.
Primary purpose: Assault
Secondary purpose: Anti-spacecraft


Type: A symmetrical subspace graviton field. This type of shield is fairly similar to those of most other Starships. However, besides incorporating the now mandatory nutation shift in frequency, the shields alter their graviton polarity to better deal with more powerful weapons, such as the neutron-carbide beams of Tamarian vessels. During combat, the shield sends data on what type of weapon is being used on it, and what frequency and phase the weapon uses. Once this is analyzed by the tactical officer, the shield can be configured to have the same frequency as the incoming weapon - but different nutation. This tactic dramatically increases shield efficiency.

Output: There are twelve shield grids on the Excelsior Class starship, and each one generates 137.5 MW, resulting in a total shield strength of approx. 1650 MW. The power for the shields is taken directly from the warp engines and impulse fusion generators. If desired, the shields can be augmented by power from the impulse power plants. The shields are now comparable to the original New Orleans class and can protect against approximately 12% of the total EM spectrum (whereas the Galaxy Class Starship's standard shields can protect against about 23%), This improvement was made possible by the multi-phase graviton polarity flux technology incorporated into the shields, which is now standard issue on Federation starships.

Range: The shields, when raised, stay extremely close to the hull to conserve energy - average range is ten meters away from the hull.
Primary purpose: Defense from enemy threat forces, hazardous radiation and micro-meteoroid particles.
Secondary purpose: Ramming threat vehicles.

Check out our open positions!.

Do you think you can write better then the writers from Startrek and you would like to let us read it. Then join up and become a character on the USS London. 

  Do you want to play a character but not want to have the responsibilties of a department head or an starfleet officer, then join up as a CREWMAN... so you can play poker or visit the holodeck without filing reports. If you want a position which is not on the manifest, then check with the CO, we can always create it.  So check out our manifest.

Join in and have fun!!!
