Off the top of my head, if I had to protect a shipping container sized object from a 737, I would bury it. Dig a hole maybe the size of a residential swimming pool, build some drainage and some concrete walls with enough space to allow the container to get back out, stick the container in, and backfill outside the walls. Put a lid on it and cover it with local soil. As a bonus: anyone trying to steal it would need an excavator of some sort. Or build an underground parking lot, park the SMR in it, put a serious door in front, and use the space above it for something else. Conventional construction underground, especially of something complex, is expensive. But much of the point of an SMR is that it’s built off site and then installed. Driving a container down a ramp or lowering one off a crane is straightforward.
