Not so secret, apparently
In today’s world, no launch or deployment of a satellite can be kept secret....the inability to tap into what it is processing classifies it. They stopped the obvious lies a while ago as far as this sort of thing....when I was in Korea in the mid ‘80s, the official stance was we had no spy birds on hand....but you could watch them circling above the base on the way up in the mornings and on the way down in the evenings....modified U2 birds.
