As our friend "TheImmortal" mentioned in a post the fact that this engine has a TVC indicates it is intended more as an ICBM since TVC for first stage SLV is not requiredI'm curious to see if they will introduce a new missile with this new engine, or keep it solely for the space program. As far as I'm aware, the Salman engine they showed before is only used for SLVs so far.
Let's look at history for a moment. The first nuclear (plutonium based) weapon was developed by the USA, and it's only delivery mode was aircraft
Later they miniaturized the nuclear system into a warhead, and constantly refined the payload/blast yield etc... over decades.
Then, working on reaching inter-continental ranges carrying a nuclear warhead and increasing diameter to carry more warheads.
Now today, theirs a certain country with 60% enrichment, very advanced centrifuges almost as capable as other countries on the edge of centrifuge tech, burried in deep mountain ranges (impossible to destroy conventionally) and road-mobile, solid-fuel ICBM capable.
They are reaching to the point we all know subliminally , and it is just a fingertip away. Instead of going through the progression like the Americans and Soviets did. It honestly looks like they are just getting all the pieces in first before. For then, a non-nuclear country would overnight become ICBM nuclear country. Of course, that is up to them to decide, doesn't mean they will actually develop a ground attack ICBM.
Pretty crazy stuff if you ask me. Whether or not a nuclear deal will happen will have big implications on the direction these guys take.
