The Low Lift Launch System is a continuation of the design that is utilized in the 4534-class Orbital Launch System, which was discontinued.  Utilizing updates to the guidance system, the Low to Mid Orbit Launch System utilizes a 3-Core First Stage Booster, and a 1-Core Second Stage Booster for all primary launches into Low Earth Orbit.

Part of the Low to Mid Orbit Launch System is the Crewed Orbiter, used to deliver personnel and a small amount of supplies to the Orbital Science Space Station and the Cargo Transporter, which is used to deliver a larger amount of supplies to the Orbital Science Space Station.

The Third Stage Booster for this Launch System was Discontinued with the development of the Medium-Lift Launch System.
The Delta-class Booster image
The Delta-class 1st Stage Booster was the Imperial Space Administration's first design at a reusible booster system to deploy satellites and other equipment into Low Earth Orbit. The big test was to build the Orbital Science Space Station. After a total number of 13 launches utilizing 7 of the Delta-class Boosters, it took 1 Month and 8 Days for the Station to be completed. After then, the system was also used to launch a multitude of Satellites for Shazbotdom News Corporation and to launch a large grouping of CubeSats for a Univesrity from an Allied nation. As of now, the booster's main process is to launch Resupply and Crewed Missions to the Orbital Science Space Station and the occasional launching of sections to the new Orbital Transfer Station.
The Gamma-class Booster image
The Second Stage Gamma-class Booster is the secondary boosting mechanism for the Low to Mid-Orbit Launch System. It's purpose is to give the push of launches to get equipment up to an orbital height of ~110km.
The Epsilon-class Orbiter image
The Epsilon-class Orbit was designed as the primary booster system for the 3rd Generation Space Capsule. Its purpose is to push the capsule into its final orbital trajectory to complete docking procedures with the Orbital Research Space Station. It is also the primary mode of transporation to return the Space Capsule back to Earth. Utilizing the engines to decelerate from orbit, it has landing legs, RCS Thrusters, and a parachute to assist in landing operations to bring anywhere from 3 to 6 Astronauts to the space staiton and back to Earth.

The updated Epsilon-class v2 Orbiter is completed and is now paired with the 4th Generation Capsule, where the docking ring is moved from sides of the orbiter to the top of the cone and the parachute is integrated into the body of the capsule and moved off of the nose cone. There is also the addition of a Launch Abort System (LAS) onto the top of the capsule, which will be utilized in case there is a catastrophic system failure. This system will eject and catapult the Capsule away from the rest of the Full Stack, where it will be able to successfully land to keep the astronauts safe.
The 4th Generation Capsule image
The high tech Capsules of the Imperial Space Administration are nearly 100% automated in terms of it's orbital capabilities. With most information shown on touch-screen displays within arms reach of the seats. There is a manual joystick behind a door undernieth the center display. This joystick is just in case that there is an issue with the onboard computer and it is needed to manually dock or undock with the Space Station. While it does not have any RCS thrusters of it's own, it does have smaller cold-gas thrusters that give it the ability to roll and pitches so that the heat shield is always pointed towards the right direction so that it doesn't burn up upon re-entry.

The Capsule's heat shield is designed so that the Capsule and Heat Sheild have a hatch at the bottom that is automated and can create a airtight seal to ensure that no damage occurs to the underside of the Capsule. This design is to ensure that if something occurs with whatever vehicle is transporting the Capsule to orbit (i.e. the Epsilon-class Orbiter that is used to transport to the Research Space Station) can be detached so that the Capsule can return to earth with minimal to no issues, losing only the Service Module that makes up the Orbiter. The Capsule has the ability to deliver 1 Pilot, 2 Service Crew, and 4 Passengers to orbit with each launch.

The Updated 4th Generation Space Capsule has been slated with enhanced biometrics. This system encodes the Capsule's system to the crew that is assigned to the mission. The capusule also has an enhanced air filtration system and cooling system to ensure the comfort of the astronaughts onboard. Each suit is integrated into the filtration and cooling system via three tubes that attach to the right side of each chair. Each suit is perfectly tailored to the specific astronaut to ensure comfort. There is a mobile computer panel that attaches to either wrist of the suit that is utilized as a control panel to adjust the airflow and temperature for the individual's suit.
The Omega-class Cargo Transporter image
The main workhorse of the Cargo Transporation Fleet for the Orbital Science Space Station, the Omea-class specialty cargo transporters are designed to connect with the lowest docking segments of the Space Station so that Scientists can unload any and all equipment and new Research Projects onto the station as quickly as possible, utilizing the large docking ports at the top end of the transport ship. The vehicle is also designed to the point that it can bring up new equipment to replace old, outdated, and/or broken computer equipment.

These Cargo Transporters are designed to have a total lifespan of 25 years before they need to be replaced. As of right now, the Imperial Space Administration has plans for at least two replacements for the Omega-class, with production of the prototypes of these two replacements. There is no official word of when these prototypes will be finished, they are being designed by two different private corporation teams. Imperial Space Expeditions Incorporated has the contract for one of the Prototypes while The Imperial Scientific University at Fairbanks is holds the contract for the second of the Prototypes.
