也顶不住,回头报复扔一个蛋蛋回去就可以了。
而且这种东西成本这么高,根本难以批量,等你能批量的时候别人家的也出来了。

当然莫斯科可以不用相信他的话,直接发一个导弹回敬纽约或者华盛顿就好了。貌似以

判的人还很个人英雄主义的事先到纽约去等核武器跟纽约人民一块儿上天堂。

HTV-2 collects unique data during several phases of second flight
Today, DARPA attempted to fly the fastest aircraft ever built. The Agency’
s Falcon Hypersonic Technology Vehicle 2 (HTV-2) is designed to fly anywhere
in the world in less than 60 minutes. This capability requires an aircraft
that can fly at 13,000 mph, while experiencing temperatures in excess of
3500F. The second test flight began with launch at 0745 Pacific Time. The
Minotaur IV vehicle successfully inserted the aircraft into the desired
trajectory. Separation of the vehicle was confirmed by rocket cam and the
aircraft transitioned to Mach 20 aerodynamic flight. This transition
represents a critical knowledge and control point in maneuvering atmospheric
hypersonic flight. More than nine minutes of data was collected before an
anomaly caused loss of signal. Initial indications are that the aircraft
impacted the Pacific Ocean along the planned flight path.
“Here’s what we know,” said Air Force Maj. Chris Schulz, DARPA HTV-2
program manager and PhD in aerospace engineering. “We know how to boost
the aircraft to near space. We know how to insert the aircraft into
atmospheric hypersonic flight. We do not yet know how to achieve the
desired control during the aerodynamic phase of flight. It’s vexing; I’m
confident there is a solution. We have to find it.”
“Prior to flight, the technical team completed the most sophisticated
simulations and extensive wind tunnel tests possible. But these ground
tests have not yielded the necessary knowledge. Filling the gaps in our
understanding of hypersonic flight in this demanding regime requires that we
be willing to fly,” said DARPA Director Regina Dugan. “In the April 2010
test, we obtained four times the amount of data previously available at
these speeds. Today more than 20 air, land, sea and space data collection
systems were operational. We’ll learn. We’ll try again. That’s what it
takes.”
According to Schulz, three technical challenges exist within this HTV-2
flight regime. They are categorized as aerodynamic; aerothermal; and
guidance, navigation and control. And each phase of flight introduces
unique obstacles within these areas.
“To address these obstacles, DARPA has assembled a team of experts that
will analyze the flight data collected during today’s test flight,
expanding our technical understanding of this incredibly harsh flight regime
,” explained Schulz. “As today’s flight indicates, high-Mach flight in
the atmosphere is virtually uncharted territory. ”
In the coming weeks, the assembled independent Engineering Review Board will
review and analyze the data collected. This data will inform policy,
acquisition and operational decisions for future Conventional Prompt Global
Strike programs—the goal of which, ultimately, is to have the capability to
reach anywhere in the world in less than one hour.
