I wouldn't say TS doesn't have it. It just isn't acknowledged and is fairly expensive. All the RTG powered swarms have to be using Pu-238, Am-241, or Sr-90 (the description implies Pu-238). Pu-238 comes from the transmutation of Np-237, which come the transmutation of U-238, which is naturally occurring.

We've had transmutation in the real world since the 30s, for lab scale, and since the 40s for industrial scale (Tritium (H3) from Lithium, Plutonium from Uranium, and Americium from Uranium being the common items). But the cost can be a bit high (current market is $5M+ for a kg of Pu-238 from Np-237).

True.
