There are always some particular things that are suppressed.
But, the thing about technology is that the more people that know about it, the faster developments come.
So, the suppressed technologies are likely in an "undeveloped" state, while the world has certainly moved ahead rapidly in other areas.
One known suppressed technology is the "magnetic amplifier". This was used in place of the "vacuum tube" by the Germans during WWII. Because of it's
various military applications, the government has suppressed this technology. That means lots of brilliant minds didn't get to tackle the problems
involving this area of research, so it is very likely "dead" or still in a "primitive" state in the hands of the military.
The "magnetic amplifier", also known as the "saturable reactor" , led to the development of very sensitive "magnetic compass" that could detect the
presence of a vehicle containing metals from a mile away, and could be used as a surveillance tool to detect the presence of enemy vehicles on land or
stealth boats and submarines in the water, in complete darkness. So, all the work involving this technology was classified, and today you still can't
find out much about it. All you will find is a few old writings from the 1950s, just after the war, before the government recognized the importance of
the tech, and classified the whole area of research. This stuff is now lost in the deep dark dungeons of above top secret tech.
My guess is that they haven't made much progress with it, since the best minds were excluded from thinking about the subject.
So, the military probably have the same level of tech there, as the Germans had back in the 1940s. Probably, with some minor enhancements using modern
technologies to complement the old tech.
