Hypersonic Missile Nonproliferation

Mordhaus jokingly says...



Also, the Japanese planes sacrificed durability for speed, maneuverability, and gun capability. Once US pilots realized this, they exploited the vulnerability because our planes were basically tanks compared to the Japanese ones.

The US had the best rocket program once the Saturn V became available in the 60s.

As of 2018, the Saturn V remains the tallest, heaviest, and most powerful (highest total impulse) rocket ever brought to operational status, and holds records for the heaviest payload launched and largest payload capacity to low Earth orbit (LEO) of 140,000 kg (310,000 lb), which included the third stage and unburned propellant needed to send the Apollo Command/Service Module and Lunar Module to the Moon.[5][6]

The largest production model of the Saturn family of rockets, the Saturn V was designed under the direction of Wernher von Braun and Arthur Rudolph at the Marshall Space Flight Center in Huntsville, Alabama, with Boeing, North American Aviation, Douglas Aircraft Company, and IBM as the lead contractors.

To date, the Saturn V remains the only launch vehicle to carry humans beyond low Earth orbit.

Hubris.

WW2 japan had fighters that flew faster, climbed quicker, had bigger guns, and turned quicker (a6m vs f4f). And we had intel reports that told us, but we ignored them because "we have the best stuff and nobody else can compete".

You see the same stuff today with China. China makes all of our microchips, all of our microelectronics, most of which are designed over there anyways (companies here just ask for a widget that does X and Y, and Chinese companies design+make it), yet we act like as if they are some technologically retarded place that only knows how to steal ip.

Russia has been at the forefront of rocketry since ww2. Nobody has systems that compare to their consistency and reliability. Not even the U.S.. The idea that Russia can't make a hyper sonic missile before the U.S., because it's Russia, is a non sequitur.

Also, Russia broke up as a country because guaranteed government jobs for all citizens, where you can't be fired and performance is not important, is going to destroy any economy. No one will produce, shelves will be empty, and money will be no more than paper. Combine that with making private business illegal (preventing people from economically helping themselves), and you have a recipe for economic disaster and social discontent.

This missile exists to swat down carrier groups on the cheap.
We're gonna need some powerful lasers, or our own hyper sonic interceptors, or else proliferation would instantly leave us isolated in the Americas (vis-a-vis power projection via conventional weaponry). Our only option for projecting power would be reduced to nuclear or nothing.

My dad was part of the unmanned missile program. I'm still email buds with one of his co-workers (now 91 years old!) They do talk amongst themselves and this was forwarded to me:



I was working at Kennedy Space Center for McDonnell Douglas and worked on the launch of this mission. I was a Guidance and Controls Engineer on the console in the firing room (the Launch Control Center). McDonnell Douglas built the S-IVb stage….the upper stage….and the one that restarted when in orbit to send the Command Module and Lunar Module on their way to the moon….

Last Humans on the Moon

ELee says...

The video was shot from the lunar rover camera and transmitted from the lunar rover's antenna. With the time delay in sending commands to the Moon, everything had to be carefully planned in advance and the tracking had to be done blind. I have attached some quotes from a website below. (Sorry for the long post..)
-----
The only photograph of the lunar liftoff was taken from Earth and had expectedly poor resolution. "Gene tried to persuade me to stay outside and take a really good picture of liftoff, but I politely declined," Schmitt joked.

As the third outing drew to a close, Schmitt clambered up the ladder of the Apollo 17 lander. Alone on the moon's surface, Cernan steered their battery-powered automobile a mile from the spacecraft and parked the rover so a video camera could record their Dec. 14 liftoff. As he climbed from the vehicle, Cernan bent down and traced the initials of his 9-year-old daughter, Tracy, in the soil. Then he literally hopped and skipped in the moon's low gravity back to the lander.

For Apollo 16 and 17, however, flight controllers did track the ascent stage. With the punch button command arrangement and a 3 to 4 second time delay, their command sequence had to be totally preplanned. I had worked with Ed Fendell for the Apollo 17 liftoff to get it exactly right for a long tracking shot. At liftoff, the action was perfect, but soon the image of the ascending capsule drifted out at the top of the frame. Ed was furious that, after all the calculations, we missed the mark. It was discovered later that the crew had parked the Rover buggy closer to the Lunar Module than was prescribed by mission plan, and the vertical tilting of the camera was too slow.
Whenever I see a clip of that liftoff I note, as the stage nears the top of frame, a cut to a film shot of the stage ready to dock with the command module. And I still think, "Darn, we could have followed that final liftoff 'til it was but a dot of light winking out as it headed for the mother ship."
