They actually had one in Trinidad, in the West Indies in the 80's. That was top secret for years. It still might be?

"Breaking the sound barrier" creates no visible effects.
Going over the sound barrier produces one of the most amazing condensation effects - so called "Prandtl-Glauert Condensation Clouds", formed by the rapid cooling of the air. You have to be really quick with your camera "trigger" to capture it, as it only occurs at the sonic barrier

Now that information would be top secret and as such would be treasonable to post...
But I can make some 'guesses' that should be okay
But right now its bed time....

So yeah, there is a lot of cool stuff hardware wise on the horizon, but I have yet to see anything convincing that leads me to believe most of this stuff is in current programs.

Just a general FYI, the new replacement shuttles are small and can be dropped from a plane.
Consider the case where we have two Black Horse type vehicles, each using JP-5/H2O2 with an Isp of 335 s. The vehicles have a dry weight of 15,000 lb and a propellant load of 180,000 lb, which assuming a required Delta-v to orbit of 27 kft/s, allows them to deliver 1,000 lb to LEO. Now, let's say that we fly the two of them off together, accelerating them jointly not to orbit, but rather to a suborbital trajectory with a velocity of 18.5 kft/ s. The two space planes are now outside the atmosphere, in free fall (i.e. zero gravity) in the immediate vicinity of each other. Let's say we now bring the two together and extend a refueling boom, allowing the 20,000 lb of residual propellant from one to be transferred to the other. The two then separate, the empty vehicle to return to Earth, the enriched vehicle to ascend to orbit with a payload of 12,000 lbs. Without any new hardware, the orbital delivery capability of the system can be increased by a factor of 12.

The biggest advantage of the manned TAV is that it is probably the most flexible platform yet proposed for space operations simply because it is under the continuous control of a human. Given an appropriate design, the manned TAV could be quickly reconfigured to deliver special operations teams, high-value equipment and supplies, or a wide variety of munitions (in much the same fashion as a high-speed bomber).22 Most important of all - the TAV can put a few well-trained people at the site of a developing conflict anywhere on Earth within 60 minutes from launch.

"These Black Horse (1) vehicles, derived from the Question Mark 2 (2) X-vehicle shown in figure 1 and described later in this paper, will be fighter-sized airframes capable of placing an approximately 5,000 pound payload in any low earth orbit (LEO), or delivering a slightly larger payload on a suborbital trajectory to any point in the world. A Black Horse vehicle could accomplish either task within one hour of completion of mission planning, assuming that the payload was available at the base and the vehicles were on alert."

Whilst on the topic of the replacement shuttles, perhaps I should take the time to remind everyone of another space plane:
.
The new name was originally posted on the website Collectspace.com in July, but NASA had not planned to announce it officially for another week or so, when it names a contractor to build the spacecraft.
International Space Station astronaut Jeff Williams let the name slip out on Tuesday, however, when he was pre-taping a message about the new name that was accidentally transmitted over space-to-ground radio.

Are you saying it was launched by a B70 Valkyrie years & years ago?
Or, are you saying there has been a B70 Valkryrie flying around in recent times?

It should be easy tell from reading my posts just what it is I said...
The first stage of the Blackstar system consisted of a Mach 3+ winged air-breathing first stage evidently developed from North American's XB-70 bomber; and an XOV manned eXperimental Orbital Vehicle lifting body second stage. The system was developed by a consortium of US aerospace companies at the behest of an unspecified US government agency.
The system was so classified that it remained unknown to the nation's top military and civilian space planners, while they labored to design, but never developed, an equivalent white-world system. Blackstar was designed to handle numerous missions: strategic reconnaissance; anti-satellite; quick-reaction small satellite launch; and delivery of small conventional warheads.

For 16 years, Aviation Week & Space Technology has investigated myriad sightings of a two-stage-to-orbit system that could place a small military spaceplane in orbit. Considerable evidence supports the existence of such a highly classified system, and top Pentagon officials have hinted that it's "out there," but iron-clad confirmation that meets AW&ST standards has remained elusive. Now facing the possibility that this innovative "Blackstar" system may have been shelved, we elected to share what we've learned about it with our readers, rather than let an intriguing technological breakthrough vanish into "black world" history, known to only a few insiders. U.S. intelligence agencies may have quietly mothballed a highly classified two-stage-to-orbit spaceplane system designed in the 1980s for reconnaissance, satellite-insertion and, possibly, weapons delivery...
The SR-3 had the same basic layout and dimensions as the XB-70. It was a completely different aircraft in detail, having variable geometry rather than fixed canards; a blended double-delta wing rather than a straight delta; fixed-upward swept combined wingtips/vertical stabilizers rather than deployable-downward swept wingtips and fixed twin vertical stabilizers; four engines in two nacelles rather than six in a single nacelle. The use of two nacelles had been proven in the North American B-1 design, and would have provided the necessary space for the carriage of the XOV on the belly. The X-15/B-70 concepts had envisioned launch from the back of the B-70, but the loss of an A-12 on 30 July 1966 while launching a Mach 4 D-21 drone had shown this to be dangerous.
