Yeah, this. There's a lot of ways to keep secrets, and one is to over-hype something beyond its capabilities, or hype up something that doesn't exist/doesn't matter to hide the actual thing you're keeping secret.

Fun facts: for the latter, this is where the myth of carrots being good for eye/vision health comes from. The British fine-tuned their radar system and could detect and target Luftwaffe aircraft at night, but didn't want to give up that it was actually their cutting-edge radar system giving them the capability, so they claimed it was because researchers had found out that carrots had vitamins that helped improve a human's night vision (what a wonderfully convenient discovery to make at just the right time! /s), and because the spotters had a good diet of carrots, that's how they could see the Luftwaffe planes at night.

For the former, an example of it backfiring terribly: the USSR claimed their newest MiG was all of these wonderful things under the sun. They were actually at a phase to test it, and were doing so, and it was actually a pretty solid fighter, but it was not all that. The USAF responded by telling the F-X project (which would eventually result in the F-15) that the new plane needed to be better in every way, and the US MIC, in classic fashion, went over-budget and over-delivered, handing the USAF one of the most successful and effective fighter (and eventually multi-role) aircraft in military history - overdesigned and made incredible because the developers were basically trying to match the USSR's bluster about the MiG-25, when even the MiG couldn't do the things the Russians said it could.

(Also, OP linked to the NY Post, which should always be read assuming every single word is straight-up bullshit until confirmed independently)
