Based on some Soviet research into reusable spacecraft, Myasischev M-19 program had a lot of really interesting design decisions, including nuclear ramjet engines.
Shown here is one of the preliminaries of M-19-2 spacecraft from 1980, using 6 hydrogen-fueled jet engines.

This might not be the most accurate depiction of this spacecraft as the info on the whole program is very hard to find, while being pretty self-contradicting and limited.

There's actually more to that than this, sources in Russian provide more a bit more insight, as well as a couple of showcase technical drawings.

Sources I used were this and this.

Drawing itself is based on this variant of the plane:

The estimable e of pi and I have been posting our timeline Boldly Going: A History of an American Space Station on AH.com

Today, I'd like to share with you some shipbucket art that I did in support of the timeline. Behold, the two winners of that universe's analog to the Evolved Expendable Launch Vehicle program:

Heimdall:

Atlas III:

Background:

In support of the Shuttle and Shuttle-C programs, NASA gets the LRB funded. With this universe not having the National Launch System program, the Defense Department / USAF gets what became the Evolved Expendable Launch Vehicle program about 2-3 years earlier than OTL. Given that, and the LRBs, Thiokol is trying to sell their solids to anyone who will buy, and they partner with Alliant Techsystems on Heimdall prior to a merger. They win one of the two spots, and the other goes to General Dynamics with their LRB-Derived booster, which they label as the "Atlas III" (It drops engines, has a centaur on top, and is built by General Dynamics - how is it not an Atlas?)

These win against a Martin Marietta proposal that looks a lot like the OTL Atlas V (probably called the Titan V here) and something else that we have left undefined.

Interesting concept, and great drawings.
