The D-SCOFF Module (D-SCOFF stands for "Deep-Space COmms interception Friend or Foe) is a comms interception device deployed on lone satellites and automated stations to intercept friendly and enemy transmissions. Good with you?
Commander Elsee Tamarillho is a 34-year-old merchant navy officer. She is young by merchant navy standards - most people reach Commander rank between the ages of 35 and 40 - yet has commanded freighters since she was 23. She has commanded seven cargo ships to this date, excluding the Vulture which isn't a cargo ship - and never was anyway, since salvage ships weren't considered cargo haulers - which is excessively young. Most people receive their first merchant ship command between 28 and 35. She climbed through the merchant ranks quickly. A week after she joined her first merchant crew - at age 17 - she was promoted from Ensign to Second Lieutenant. This made her the youngest SL ever in recorded Kytheran history, both naval and merchant. She made Lieutenant Commander at 22, and served as a second-in-command on the NKCS Profitable Journey (all Kytheran merchant ships have names like this, it's said to be a lucky charm) before her CO retired a few months later. Then, she received her first command.
She made Commander at age 26, again giving her a mention in the Kytheran history books - well, merchant shipping archives anyway. Her previous crews say she's "an experienced commanding officer, who knows what to do at every turn. She is highly respected on the ship. The crew greatly looks up to her, yet she's not arrogant. She's the last person to shout at a rookie for doing something wrong. She's simply a fantastic person."
Antimatter plasma engines are old-fashioned engines, which rely on a fusion torch-like drive system, yet it uses a mixture of rapidly-fusing plasma and antimatter for thrust, instead of simply plasma. Semi-reactionless photon drives are far more complicated.
They rely on the natural flow of photonic particles to accelerate the ship and to steer it. It does have a semi-secondary photon torch engine, which it mainly uses for acceleration to higher speeds, after which the reactionless drives take over. This is why it's called semi-reactionless.
The reactionless drives rely on photon capturing and direction conduits lining the entire outer hull of the ship. They emit passive quantum fields, essentially "capturing" photons in the field. The photons are then directed to the opposite direction the ship steers - if it's going dead ahead, they're directed backwards, if they're making a 50 left, they're directed to 50 right - which in itself does not provide much thrust, but the special subquantum generators take care of that.
The subquantum generators emit active seeking fields of sub-elemental particles, essentially the particles that existed before the Big Bang as Kytheran astrophysicists have proven. A chain reaction among these particles created the Big Bang. These particles have highly unusual qualities, and are not understood at all. However, they can be used for several things already - among which a rather strange form of quantum manipulation.
Photons are essentially oversized underpowered quantums. The sub-elemental particles "grab" the photon as it's directed by the passive quantum fields. The photon
is being held in place. This way, the photons are utterly still and do not move. The quantum fields still push it, however. This force is thus not transferred to the photon but translated into forward motion. That is how semi-reactionless photon drives work at high speeds.
Hope you're still with me after that rant
