Pathfinder long range science vessel

The Pathfinder-class was a type of science vessel fielded by the Federation Starfleet beginning in the year 2410. It was an advanced variant of the Intrepid-class starship of the 2370s decade.

When planning for Operation Delta Rising began, the Starfleet Corps of Engineers decided that an updated version of the Intrepid-class was necessary. Most of the technologies used in the Pathfinder-class were tested aboard USS Voyager before it departed for the Delta Quadrant in 2410. With the approval of Rear Admiral Tuvok, the class entered full production.

The Pathfinder-class featured a secondary deflector dish and could be equipped with the ablative generator pioneered on later Intrepid-class vessels, as well as the nadeon detonators used on Bellerophon-class starships. In addition it could deploy an Aeroshuttle from a berth at the bow to assist it during combat.

In the 25th century, the design of the Pathfinder-class long-range science vessel allowed its commanding officer to choose from different designs of livery, which could be modified further at starbases. These options were numbered Types, Upgrade and Veteran.

Furthermore, the installation of deflector shields from specific factions modified the hull appearance, including shields from the Reman Resistance, the Breen Confederacy and the Dominion.

1 - Depleting the MDC of the Engineering Section will put the ship out of commission. All internal systems will shut down, including life support and internal gravity.

1B - Destroying the Bridge will automatically switch control to main engineering in the engineering section. Once control is established in engineering the efficiency of the vessel will only be affected as follows: -5 to all combat rolls and attacks per melee are halved.

2 - Destroying the main sensors will deprive the ship of all forms of long range communications, radar and targeting. The range and targeting capabilities of the secondary systems are equal to that of a shuttlecraft at best. The ship can still operate, but is at -3 on initiative, -3 to strike, and number of attacks per melee of the weapon systems are reduced by half.

3 - Destroying the main hanger, the ship will not be able to deploy any craft until it is repaired. Under normal operations the carrier can launch or recover up to 3 shuttles per melee.

4 - Depleting the MDC of the the warp nacelles will force the ship to rely on its Impulse engines. Depleting the MDC of the Impulse engines will leave the ship adrift in space with very minimal movement allowed by its guidance thrusters. If in an atmosphere, the ship will crash.

5 - Shields regenerate at 600 mdc per melee. Only if a generator is damaged will the ability for shields to regenerate be hampered

Quantum Slipstream Drive: Transwarp 34+. Transwarp has theoretical upper "speed" limits of 100s of Lightyears per second but due to navigational difficulties, anomalies and dangers, travel velocities are typically limited to approximately 1000 light years per hour when used.

HOLODECK: This facility creates an artificial yet fully interactive and immersive holographic environment for those inside to take part in. A vastly wide variety of places and locations can be duplicated or programmed into the computer. The system is advanced enough so items or "beings" that are to be physically interacted with are imparted with a forcefield contoured to their outer shell to allow physical contact between living participant and holographic representation. Replicators are also employed to further enhance the immersion of the facility so that if a liquid is thrown or fallen into, or food spilled and so on, those involved will end up wet, stained, slimed, etc. Any matter resources used in this manner are immediately recycled back into the matter storage units for reuse. The facility has safety protocols set at default to avoid grievous injuries or unauthorized creation of sentient programs and weapons/items. This can be overridden of course but takes a high level command authorization to do so. Th Pathfinder class has 4 such facilities on board. One of large size (1000 square feet of floor space), one of medium size (approximately 700 square feet of floor space), and 2 small of size (500 square feet of floor space).

MODULAR MISSION BAYS (2): Located in the rear of the engineering hull, these two bays can be configured for a variety of purposes based on mission profile. Typically reconfiguration needs to be done while docked at a starbase. Current configurations include: Runabout Launch Bay (1 Danube class Runabout), High Capacity Advanced Medical Suite, Advanced Science Lab, MACO Company HQ, Consumables Storage for mission extension, Luxury Passenger Accommodations, and General Cargo space.
