Zeitleiste class

The Zeitleiste-class was a Starfleet timeship first introduced in the early 2480s. It was the first Timeship created by Starfleet and was created by joint operations by future Starfleet as well. Zeitleiste-class had a presence in the First Temporal Crisis.

Design and development
The Zeitleiste-class was the first starship in to be created to the full intent of being a commissioned timeship. It's design took place in the Luna Construction Facility for over 3 years, starting on stardate 155859.3.

The enhanced warp core (convective core) was thought of and designed at Utopia Planitia under high confidentiality. It was believed either Richard D. Givens or Andrew Saninero, the both of them, or another Engineer thought up the design.

Confidential and enhanced systems were built in 2 different time frames, 2 public facilities (under confidentiality) and 1 highly classified facility.

The launch of the Zeitleiste-class was allowed when finalized scans by Starfleet DTI-Engineering collected enough data to classify the ship as ready for service.

Command and control systems
The main bridge of the Zeitleiste-class was ovoid and consisted of 6 primary systems.

Located in the back was a 4 m wide wall consisting of 6 consoles for 2 different systems. In the center was Master Systems Display, it was flanked by 2 control consoles.

Left and right of these stations were the Temporal systems, experimental, they were the beginning for Starfleet's temporal sensors, moderation of the timeline, etc.

To the starboard was the Science station. Controlling sensor sweeps for specific particles, astronomical phenomena, etc. Next to that was the operations station. A little ways back of that was a turbolift. Behind that were 4 seats designated to 3 systems/people. Beginning at the front was communications, overseen by 2 comm officers. Behind them was conn which was accompanied by the First Officers station. Behind the FO station was the Command chair, on the side a console allowed ship-wide captains clearance control and oversight.

Beginning at the port side of the bridge was the engineering station. Multiple basic and essential ship functions could be halted, regulated, monitored, achieved et al. Specifically a warp core ejection. Finally ahead of that was the tactical station, practically in control of ships weapons, shields, ablative generator, the temporal apparatus (Phase Inversion Device was manned by science) et al.

There were 2 more turbolifts on either side of the engineering station.

Propulsion systems
The Engineering room on Zeitleiste-class starships were very sophisticated. They were located on deck 11. In stead of consisting of a standard warp core with a M/ARA, it had a Convective Core, a highly sophisticated and experimental engine. This allowed the same matter/antimatter and electro-plasma flow to be used [as of 2480s] constantly for 11 hours. Unlike the 4+ petadyne output, the maximum output in the Convective Core had to be minimized to 2.3 petadynes to make sure the Convection Matrix could keep up with the flow.

Warp Core Ejection
In the case a warp core beach takes place, there are multiple actions and phases which could be took to prevent/hinder a breach:

Phase 1 (Beginning of Breach)

 * A Level 10 Containment field goes up
 * Electro-plasma reading are subsequently locked onto and sent into the bussard collectors [If they're empty, if not, they're dumped]
 * Matter/Antimatter leakage is ceased/hindered by decompressing and exposing all of Engineering to space [Antimatter and Matter do not have reaction to dark matter]

Phase 2 (Phase 1 is unsuccessful)

 * The Core is ejected, a straight tube below the core opens and highly compressed air of 9.3 psi is released, removing the core
 * Residual matter and antimatter is nullified through further decompression or being isolated and sorrounded by containment fields
 * If this works, teams are sent after a period of time to repair and assess any damage or loss

Phase 3 (No success whatsoever)
Due to the significance and volatility behind these ships missions, it was a constantly changing variable on the probability of a breach.
 * Priority 1 Distress signals are sent to all Federation members and the ship is abandoned
 * The ship self destructs
