An Aerojet concept for a boost-phase ICBM interceptor.
This would be a space-based anti-missile system composed of two high thrust solid rocket motors and a kill vehicle composed of a substantial set of optics, some impressive late 1980’s computers and most likely a hydrazine monoprop divert system. The missile would be meant to physically impact an ICBM while still being lofted by the first stage; this is an bigger, slower and brighter target than the later, faster, smaller stages and warheads, but you have to be *fast* to reach out and tag a missile in the first moments of flight.
Soon to compete with SpaceX, the Rocket Lab “Neutron.” Building on their relatively dinky Electron, the Neutron will be able to orbit 8 metric tons (including manned payloads) and will feature a reusable first stage much akin to the Falcon 9 first stage.
It looks to be substantially stubbier than Falcon 9 which should make it much more stable on the landing pad which will likely be a ship or platform out at sea.
Rocket Lab is technically an American company, but the founder is a New Zealander and many launches occur from there as well. Much of the Electron manufacturing occurs in New Zealand; the 3D-printed rocket engines are made in California.
Rocket Lab, like SpaceX before it, should cause many, MANY heads to hang in shame. Who? Well, let’s start with the likes of Boeing and Lockheed. Those titans of the aerospace world should have had this sort of capability *decades* ago. But they chose not to. And the best they’ve come up with is the as-yet unflown “Vulcan,” which is *lame* comparatively. Who else? Oh… how about the United Kingdom? They used to have a planet-spanning empire. They used to have a pretty snazzy launch vehicle of their own, the Black Arrow… which they abandoned fifty years ago. And now New Zealand has not only surpassed *all* of the British Empire with their Electron (dinky as it it, its payload still exceeds that of the Black Arrow), if the Neutron comes along – which there’s no reason to suppose it won’t, though the initial launch date of 2024 might prove optimistic – then the UK will look *even* *worse.*
If Neutron works, then there’ll be no excuses whatsoever. Every nation on the planet *should* have their own launch capability… and in a number of cases, such as the US, their should be *dozens* of new launch vehicles competing to prove who can launch the most for the least.
APR Patrons and Subscribers today helped crowdfund the purchase of a Boeing blueprint, an inboard profile diagram of the 2707-300 SST. An overly expensive item became reasonably affordable, and will be provided to each of the funders as high resolution scans in full color (and cleaned-up grayscale).
Every one of those was proposed for alternate roles, from truck-towed and truck-launched land based strike missiles to air-launched and ground-launched satellite boosting systems. And they very likely *could* have done that. But they are just not really well suited for any role but sea launched ballistic missile due to the somewhat tricky propellants they use… high energy propellants so they can function adequately while still being able to fit in a small submarine. But for above-ground systems, they’d be somewhat dubious. The environment within a submarine is pretty consistent. For a missile stored in a warehouse and then hauled aloft by an airplane? The thermal and vibration environments will be highly variable.
This photo has popped up online before, but usually in pretty crummy resolution. It’s taken from “Aerojet – The Creative Company” and shows a mockup for a Titan-derived first stage booster rocket. It has double the engines of the standard Titan core stage, either two or four engines depending on how you want to count the LR-87 engines (one set of turbopumps, two combustion chambers) married to a 15-foot diameter core. This is described as a booster designed to loft the Zenith Star space-based laser weapon test system (the ZS was described and illustrated in US Spacecraft Projects #1). Documentation on this specific booster has always been somewhat lacking, though there have been quite a number of Large Diameter Core Titans designed by Aerojet and Martin over the years.

A video about the Boeing Resource Carrier designed to fly oil from far northern Canadian sites to ports. One wonders if this concept could be employed today to take the place of the recently cancelled Keystone pipeline…
One of the things about art is… what’s the “right” version? These days most concept art is probably produced digitally so the colors are mathematically defined, at least in the original. They are of course easily tweaked… but the original can in theory be infinitely reproduced without alteration. But with old-school art, reproduction methods varied in accuracy. Photos would make paintings look different based on lighting and film stock and a myriad of other variables. And then simple *time* causes colors to change and fade in prints. So… what’s “right?” Whatever looks best, I suppose.
Recently for sale on ebay was a display model of the Saro “Princess” turboprop flying boat, as Convair planned to modify it into a nuclear-powered research prototype. This late 50’s design was ballsy if nothing else: a nuclear reactor would be installed within the fuselage, providing superheated air from the reactor to the inboard above-wing modified turboprops. Unlike the NB-36H, this aircraft would have been actually powered by the reactor.
