`Alvin and Sea Cliff deep-ocean research submersible development`

Aside on Navy funding categories. Alvin had its 50th anniversary the week before; Tom notes it's not the same Alvin (rebuilt twice, most recent ~5 years prior at ~$40M). Mentioned as an example of 7-series prototype-build money.

So if they built the Sea Cliff submarine, or earlier built the Alvin submersible back in the 60s — just last week the Alvin had its 50th anniversary, which is sort of a joke because it's not the same Alvin. It's been reborn twice, most recently about five years ago as a completely from-the-ground-up new vessel. That would be bigger money — tens of millions of dollars to build something like the Alvin. The new Alvin, I think, cost about $40 million.
