Apex Basics

Apex is Rocket Science Co's heavy-lift launch vehicle, and its' launch capability shows it. At 112.2m, 4m wide (excluding the side boosters) and featuring 12 engines it can carry 75 metric tons to LDO. The main booster has 4 RSC-RE4 engines and 4 strap-on solid rocket boosters, all together the might Apex can produce 63.3 meganewtons of thrust. Next is the upper stage. The upper stage has 4 RSC-RE4 vacuum optimized engines, which can burn for just a little over 4 minutes. Though don't challenge their ability to be efficient, as each engine can produce over 1,200 kN of thrust allowing for faster orbit completion or transfer orbits.

The LONG History of Apex

Rocket Science Co began to plan a heavy-lift launch vehicle in November of 2020, as part of their venture to reach Cyrloo in mid 2021. Then some time in December we made made it official, Alpha would be our heavy-lift launch vehicle and would be ready by February as of next year. As you can see Apex wasn't even called Apex, instead Alpha.

Another reason we also planned Alpha was to expand our variety of rockets, as we non of those rockets were capable of reaching other planets in the Jundroo System. In addition this would allow for customers to have more freedom with rocket selection, and therefore this will allow customer to choose the right rocket for the right purpose.

After rigorious planning, filled with hiccups and setbacks Alpha; it was now called Apex was ready to be unveiled in April two months after it's original release date. Although, our team was working simultainouly with Bravo 10 V5 1.2 and the monster Omega 1.

The Future of Apex

At this stage Rocket Science Co plans to keep Apex a single variant, to keep everything organised and we already have Omega 1 aviable for usage.

Probably in the near future we might have a Apex Heavy 1 variant, with better efficiency than better thrust output to help cope with further space exploration. As for the time being we just plan to keep it a signle variant, Apex 1.
