story identification - 70s/80s book: Cold-war Psychic superweapons

I read this quite a while back, part of my parents library (they're in their 50s now)
I think the book was probably published in the 70s or 80s, my copy was paperback. I don't recall the cover art, but I have vague recollections of a satellite on the cover and maybe blue with grid-lines below it?

I've made concerted efforts to find it again but to no avail. My parents don't remember it either, but mum's an avowed book-aholic and buys a lot of books, reads them once and forgets about them, so that's not so surprising.

The key parts I remember:

• Both the Soviets and Americans were working on psychic techniques and technologies, with real and tangible results including Remote Viewing. MK-ULTRA was explicitly namedropped in relation to the American psychic program.



• The Soviets and Americans both had orbiting superweapons, One was a microwave laser (or something very similar) and the other used slivers of the brains of psychics to blow people's brains up in a wide area.


• A super-psychic (male) took offence to the state of the cold-war and took control over the orbital weapons by manipulating the onboard computers psychically.


• There's a gruesome description of a psychic weapon being tested on monkeys in a lab, the POV character throws up afterwards in horror.


• I think there might have been more than one POV character.


• There's an extended description of the psychic orbital weapon as experienced by people in its area of effect. Similar to the monkeys, it builds up, starting with alzheimer-esque hand-shaking and building up to seizures and screaming before their brain liquifies fully and either comes out the nose and ears or outright blows the skull open. (this is one of the more vivid recollections I have of the book)


• I remember that the super-psychic was working wholly alone and did most of his psychic stuff from motels halfway around the world from events.


• I believe the super-psychic also killed other psychics explicitly.


• The weapon satellites had code-names


• Both weapons were used on cities in the course of the story


• I vaguely recall an office building getting targeted specifically at one point.

Answer

This sounds like Star Fire by Ingo Swann published in 1978.

Your plot points match my recollection of the story. but I don't have access to a copy right now to confirm.

From memory Star Fire has

• a protagonist who becomes a super psychic


• he discovers psychic weapons programs being run by the USSR/USA


• he intervenes to shut down those programs?


• a one point he hides by pretending to be in a coma



• there are lots of remote viewing scenes as he learns about the weapons programs

There is also another answer referencing this book that mentions the graphic scene where a weapon is tested on monkeys
