I'm sure that the government uses chrome and I can't see them letting them shut down completely. I read that the epa won't let edelbrock build another foundry in the states even if they shut down the one in California, that's why it's still there.
The government has been at the forefront of developing chrome alternatives for decades. There are fewer and fewer places it's used or even allowed within government or military parts and systems. They're still out there, but dwindling by the day. Most new designs and procurement efforts specifically forbid chrome of any kind in the designs.
