I think we can assume that if the potential gain is large enough, the US or other high tech economies (China/Japan/Korea/Russia/Singapore/France/Italy/etc) are definitely capable and willing to expend significant sums. For example, the fragments of recent NorK missiles. If they had any computer or radar fragments left, they would be analysed, even if it cost $100M. Also, military cryptographic processors, especially for strategic or space comms.
