10 Type IX phaser arrays, 1 Dual Tube Quantum Torpedo Launcher (Fore), 1 Rapid pulse fire photon torpedo launcher (Aft)


Phaser Array arrangement: Three dorsal arrays on the saucer section, one for the forward, starboard and port sides. These arrays are duplicated on the ventral side of the primary saucer. Two smaller arrays cover the aft side firing arcs, are mounted on the nacelle pylons.  Two small arrays cover the aft firing arc and are located on the aft, dorsal portion of the saucer section.

Phaser Array Type: The Ambassador Class starship utilizes the Type IX system. The eight arrays are all type IX arrays. 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 IX turret can discharge approximately 3 MW (megawatts).

Phaser Array Range: Maximum effective range is 300,000 kilometers.

Primary purpose: Assault

Secondary purpose: Defense/anti-spacecraft/anti-fighter



Arrangement: One dual tube fixed-focus Quantum torpedo launcher, located just above the main deflector dish in the neck of the vessel.  A second single Photon Torpedo launcher firing dead aft is located on the after portion of the engineering hull just below the Main Shuttlebay Hangar.   These launchers are the second generation of automated, high-speed launcher originally found on the Excelsior Class starships, also know as  rapid pulse fire launchers.  Since the launch of the Ambassador Class, however, the vessel has had continuous upgrades to keep the vessel up to date with modern Torpedo Weapon technology. 

Type: Mark Q-II Quantum Torpedo and 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 Security/Tactical Officer.

Payload: Ambassador Class starships can carry a maximum of 250 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 Ambassador Class starship, and each one generates 145.9 MW, resulting in a total shield strength of approx. 1750 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.




Long range and navigation sensors are located behind the main deflector dish, to avoid sensor "ghosts" and other detrimental effects consistent with main deflector dish millicochrane static field output. Lateral sensor pallets are located around the rim of the entire Starship, providing full coverage in all standard scientific fields, but with emphasis in the following areas:

  1. Astronomical phenomena
  2. Planetary analysis
  3. Remote life-form analysis
  4. EM scanning
  5. Passive neutrino scanning
  6. Parametric subspace field stress (a scan to search for cloaked ships)
  7. Thermal variances
  8. Quasi-stellar material

Each sensor pallet (twenty in all) can be interchanged and re-calibrated with any other pallet on the ship.

Warp Current sensor: This is an independent subspace graviton field-current scanner, allowing the starship to track ships at high warp by locking onto the eddy currents from the threat ship's warp field, then follow the currents by using multi-model image mapping.

Scanning Ranges:
Tactical/Targeting Scanners: 0.78 Light-Years (LY)
High Resolution (
Short Range): 1.89 LY
Low Resolution (
Long Range): 31 LY



There are twenty independent tactical sensors on Ambassador Class Starships. Each sensor automatically tracks and locks onto incoming hostile vessels and reports bearing, aspect, distance, and vulnerability percentage to the tactical station on the main bridge. Each tactical sensor is approximately 50% efficient against ECM, and operates modestly in particle flux nebulae -  measuring somewhere between 40-50% accuracy on primary and secondary scans.



One small stellar cartography bay is located on deck 14, with direct EPS power feed from engineering. All information is directed to the bridge and can be displayed on any console or the main viewscreen. The Chief Science Officer's office is located next to the Stellar Cartography bay.



There are Fifteen science labs on an Ambassador Class starship; five labs are on deck 7 - adjacent to Sickbay, 5 labs are on deck 8, and 5 multifunction labs on deck 16. The 5 labs on deck 5 are bio-chem-physics labs that can also be reconfigured for Medical labs and used primary by the Medical staff. The 5 labs on deck 7 are a mixed batch; two are bio-chem-physics, two are XT (extra-terrestrial) analysis labs, and one eugenics lab.  The final 5 on deck 16 are multi-functional labs that can be equipped for various experiments.



A probe is a device that contains a number of general purpose or mission specific sensors and can be launched from a starship for closer examination of objects in space.

There are nine different classes of probes, which vary in sensor types, power, and performance ratings. The spacecraft frame of a probe consists of molded duranium-tritanium and pressure-bonded lufium boronate, with sensor windows of triple layered transparent aluminum. With a warhead attached, a probe becomes a photon torpedo. The standard equipment of all nine types of probes are instruments to detect and analyze all normal EM and subspace bands, organic and inorganic chemical compounds, atmospheric constituents, and mechanical force properties. All nine types are capable of surviving a powered atmospheric entry, but only three are special designed for aerial maneuvering and soft landing. These ones can also be used for spatial burying. Many probes can be real-time controlled and piloted from a starship to investigate an environment dangerous hostile or otherwise inaccessible for an away-team.

Requirement of a warp capable shuttlecraft was issued in the 2340s. The development of such a warp capable shuttle was to be capable of short and medium
range missions and assignments. The original Type-10 runabouts were created, but soon we found to be limited in their size. The development of the Danube-Class
runabouts began in 2363. They were first introduced in 2368. The Danube-Class runabouts feature a front cabin for four. The pilot, co-pilot/operations, and two mission specialists.
There is also a two person transporter in the rear of the front cabin. Aft of the front cabin are the mission specific modules. Based on the nature of the modular design, the
runabout can be converted to other mission-type specific requirements such as personnel transporter, cargo transporter, scientific expeditions, tactical assignments,
prison transports, medical transports, etc.  There is also an optional photon torpedo module on the top of the Danube-Class runabout.

The impulse engines are constructed from eight fusion reactors divided into two sets, space-time impulse drive coils, and vectored exhaust directors. The engines also
include intake vents for atmosphere or interstellar travel. When maintenance is required, the impulse drive assembly can be removed.

The Danube-Class computer core, which measures 2.3 x 2.1 x 1.3 meters, is located under the cockpit. The core is a standard isolinear unit with 186 isolinear banks and
53 command pre-processors. Sub nodes are installed throughout the runabout and are connected to the core by standard optical data network relays.

Type-8 Personnel Shuttle


Type:  Light long-range warp shuttle.
Accommodation:  Two flight crew, six passengers.
Power Plant:  One 150 cochrane warp engine, two 750 millicochrane impulse engines, four RCS thrusters.
Dimensions:  Length, 6.2 m; beam, 4.5 m; height 2.8 m.
Mass:  3.47 metric tones.
Performance:  Warp 4.
Armament:  Two Type-V phaser emitters.

Based upon the frame of the Type-6, the Type-8 Shuttlecraft is the most capable follow-up in the realm of personnel shuttles.  Only slightly larger, the
Type-8 is equipped with a medium-range transporter and has the ability to travel within a planet’s atmosphere.  With a large cargo area that can also
seat six passengers, the shuttle is a capable transport craft.  Slowly replacing its elder parent craft, the Type-8 is now seeing rapid deployment on all
medium to large starships, as well as to Starbases and stations throughout the Federation.



Type:  Light short-range warp shuttle.
Accommodation:  Two flight crew, six passengers.
Power Plant:  One 50 cochrane warp engine, two 750 millicochrane impulse engines, four RCS thrusters.
Dimensions:  Length, 6.0 m; beam, 4.4 m; height 2.7 m.
Mass:  3.38 metric tones.
Performance:  Sustained Warp 3.
Armament:  Two Type-IV phaser emitters.

The Type-6 Personnel Shuttlecraft is currently in widespread use throughout Starfleet, and is only recently being replaced by the slightly newer Type-8 Shuttle of similar design.  The Uprated version of this vessel is considered to be the ideal choice for short-range interplanetary travel, and its large size makes it suitable to transport personnel and cargo over these distances.  A short-range transporter is installed onboard, allowing for easy beam out of cargo and crew to and from their destination.  Atmospheric flight capabilities allow for this shuttle type to land on planetary surfaces.  Ships of this type are currently in use aboard virtually every medium to large sized starship class, as well as aboard stations and Starbases.

The Type-6 is perhaps the most successful shuttle design to date, and its overall structure and components are the foundations upon which the Type-8, -9, and -10 spaceframes are based.



Type:  Heavy long-range warp shuttle.
Accommodation:  Two flight crew, two passengers.
Power Plant:  One 250 cochrane warp engine, two 800 millicochrane impulse engines, four RCS thrusters.
Dimensions:  Length, 9.64 m; beam, 5.82 m; height 3.35 m.
Mass:  19.73 metric tones.
Performance:  Warp 5.
Armament:  Three Type-V phaser emitters, two micro-torpedo launchers, jamming devices.

Developed specifically for the Defiant-class starship project, the Type-10 Personnel Shuttle is the largest departure from the traditional role of an auxiliary craft that Starfleet has made in the past century.  Short of a dedicated fighter craft, the Type-10 is one of the most powerful auxiliary ships, with only the bulkier Type-11 being more heavily equipped.  Nonetheless, the shuttle sports increased hull armor and the addition of micro-torpedo launchers, as well as a suite of tactical jamming devices.  A larger warp coil assembly, as well as torpedo stores, makes the Type-10 much more heavier then other shuttles.  Elements from the Defiant-class project that were incorporated into the shuttle include armored bussard collectors, as well as a complex plasma venting system for use during possible warp core breech situations.  This bulky craft is equipped with a powerful navigation deflector that allows it to travel at high-warp, and a complex sensor system makes this shuttle suitable for reconnaissance work.  Able to hold its own in battle situations, the Type-10 is seeing limited deployment on Defiant-class starships, as well as border patrol vessels and combat-ready ships.
