No it's not. It stopped being approved for usage by NIST a few years ago.

Really? 3DES still appears here, https://csrc.nist.gov/projects/block-cipher-techniques, with DES and Skipjack being called out as deprecated.

That page says that 3DES is prohibited from usage in new applications and is prohibited for encrypting more than 1 GB of data, since 2017.

The attached documents have additional information on implementation and (non) usage, including deadline to migrate legacy military systems. It's sadly quite cumbersome to go through the tens of PDF to find the relevant information.

112-bit keys are still allowed precisely because of 3DES.
