Starship Systems


Short Range Sensors

Velocity: warp 9.9999
Range: 40,000 km

Short-range sensors provide detailed scans of nearby objects or the surface of a planet while in orbit. Without short range sensors transporter locks and lifeform identifications cannot be established by the starships systems.

Long Range Sensors

Velocity: warp 9.9999
Effective Range: 5 LY
Maximum Range: 17 LY

Without long range sensors, the ship cannot navigate safely at warp speeds. Within the confines of a solar system, providing a celestial object does not block the array, the long-range sensor array is capable of providing nearly instantaneous high-resolution information. However, at the maximum range of 17 LY a sensor pulse transmission would take approximately 45 minutes to reach the destination, and another 45 minutes to return the data reflection with a low resolution yield.

Navigational Deflector Array

The navigational deflector array houses the long-range sensors and the graviton plow emitter. The array accelerates the sensor signals and graviton beam to high warp velocities head of the ship to detect and push aside navigational hazards from the course of the vessel. The graviton plow sweeps thousands of kilometers ahead of the ship.



Velocity: warp 9.9999
Range: 40,000 km

If the shield frequency of a destination is known, it is sometimes possible to adjust the Transporters to pass through. However, own ship's shields must be down for transporters to operate. The ship cannot transport at warp speeds unless the target destination is also traveling consistently at the same integral warp velocity, within the same warp field.


Velocity: warp 9.9999
Range: 40,000 km

Effective tractor beam range varies with payload mass and desired delta-v (change in relative velocity). Assuming a nominal 5m/sec^2 delta-v, the primary tractor emitters can be used with a payload approaching 7,500,000 metric tons at less than 1000 meters. Conversely, that same delta-v can be imparted to an object massing about one metric ton at ranges approaching 20,000 kilometers. Tractors can be adjusted to pass through shields if the shield frequency is known, otherwise not effective when target has shields raised. The ship cannot establish a tractor beam at warp speeds unless the target is also traveling consistently at the same integral warp velocity, within the same warp field.


In a battle alert situation shield modulation frequencies and bandwidths are randomly varied to prevent a Threat force from penetrating shields by matching frequency and phase. Conversely, when the frequency characteristics of a weapon or hazard is known, it is possible to dramatically increase deflector efficiency by adjusting the shielding frequencies for optimal defense against the incoming weapon or hazard.



Velocity: c = 300,000 km per second
Effective Tactical Range: 300,000 km


Phasers can only be used when own ship is at sublight speeds. Phasers can be adjusted to pass through shields if the shield frequency is known.


Velocity: 9.99
Effective Tactical Range: 15 km -to- 3,500,000 km
Warhead Yield: medium

Torpedoes are the weapons of choice at warp speeds. Torpedoes can be adjusted to pass through shields if the shield frequency is known. The maximum cruising velocity will be at a 75% increase of own ship's speed, not exceeding the speed of light at sublight velocities, and not exceeding warp 9.99 at warp speeds. Theoretically, the torpedo can coast indefinitely at sublight speeds, however it can only sustain a warp field for limited time. Sacrificing warhead yield can increase this range. When fired within 25 km of the target, the firing ship is required to take rapid evasive action to avoid damage from the warhead blast of it's own torpedo. Firing an armed torpedo at range of less than 15km is not recommended, and hazardous to the firing vessel.


Personal Communicator

Velocity: warp 9.9999
Range: 500 km (unboostered)

To extend the communications range of a personal communicator a starship must be within 40,000 km to establish a sensor lock / computer link with the communicator to boost the signal. Without boostering, personal communicators are limited to a line of sight 500-kilometer range, and are subject to common geological and Electro-Magnetic interference.

Starship Communications

Velocity: warp 9.9999
Range: 22.65 LY (unboostered)

To extend communications range from a remote location on the edge of explored space, a starship must be within 22.65 LY of a Subspace Relay/Booster Platform to link communications with the Starfleet Subspace Network, and the Federation Civil Communications System. Such long-range communications can take months of subspace travel before being received by the intended party.
