That&#x27;s nothing. The real money will be in missile defense. Currently a single ground based interceptor costs, according to wikipedia [1], at least $74 million. Such an interceptor carries one kill vehicle [2] that weights about 64 kilograms. A Starship is able to put 100 tons of stuff in orbit, so it could send a huge swarm of such kill vehicles which could take care of hundreds of incoming threats. And because the Starship is reusable, this could all happen for cheaper than a single current interceptor. Starship has the potential to magnify basically overnight the US&#x27;s missile defense capability by a factor of 100. Now you can do the math: F-35 has a lifetime cost north of 1 trillion, one single aircraft carrier has a price tag of $13 billion, one B-21 Raider is expected to cost about $600 million. How much would the US be willing to pay for an airtight ballistic missile defense system?<p>[1] <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Ground-Based_Interceptor" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Ground-Based_Interceptor</a><p>[2] <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Exoatmospheric_Kill_Vehicle" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Exoatmospheric_Kill_Vehicle</a>

I&#x27;m always wary of media reporting on Spacex. Reuters headlines on the starship launch was &quot;Elon Musk&#x27;s Starship explodes minutes after first test flight&#x27;s liftoff&quot; and &quot;Spacex confirms loss of starship at end of third test flight&quot; ABC &quot;SpaceX Starship rocket disintegrates mid-air after launch&quot;. And the 60 Minutes piece implying that that Nasa couldn&#x27;t rely on SpaceX because Starship. &quot;RUD is SpaceX speak for &quot;our Starship rocket just blew up again&quot; &quot;And now you&#x27;ve seen some of the perils of relying on SpaceX&quot; Rather than taking about how the Falcon 9, that Nasa does rely on, is the most reliable rocket in history: <a href="https:&#x2F;&#x2F;arstechnica.com&#x2F;science&#x2F;2022&#x2F;02&#x2F;spacexs-falcon-9-rocket-has-set-a-record-for-most-consecutive-successes&#x2F;" rel="nofollow">https:&#x2F;&#x2F;arstechnica.com&#x2F;science&#x2F;2022&#x2F;02&#x2F;spacexs-falcon-9-roc...</a>

We were promised mars, but instead we got ubiquitous aerial surveillance of all human movement.

Musk has a long history of having opinions on policies. Why would DoD&#x2F;CIA&#x2F;NSA trust him with anything?

Good! I&#x27;m tired of US tech giants clutching pearls about working with their own government.

I mean… yeah…? They’re basically a government contractor with a side hustle, and it doesn’t take a politics wonk to figure the American government spends more on the military than on NASA.<p>&gt; hundreds of satellites… $1.8 billion contract signed in 2021 with the National Reconnaissance Office (NRO)… The contract signals growing trust by the intelligence establishment of a company whose owner has clashed with the Biden administration and sparked controversy, opens new tab over the use of Starlink satellite connectivity in the Ukraine war, the sources said.<p>Uhhhh I meaaaaan kinda? It’s from 2021, and I doubt the NRO is open to switching partners for any reason, much less ephemeral foreign policy ones. Plus who would they even switch to, blue origin? They presumably are already behind 90% of existing NRO satellites.<p>As far as national security is concerned, I’m only slightly worried that the obvious Russian asset that is Elon Musk would be able to do any damage via this contract. To say the least, the NRO is a secretive and security-conscious organization. If I trust anyone to institute proper information security protocols, it’s them.<p>Well, other than that one time the president leaked their tech for fun at a press conference lol

I mean, it&#x27;s a commercialised payload launch system. I&#x27;d be surprised if they weren&#x27;t.

Shocked. Just shocking... (useless comment I know)

&gt;If successful, the sources said the program would significantly advance the ability of the U.S. government and military to quickly spot potential targets almost anywhere on the globe.<p>Until satellites get destroyed by &quot;accidents&quot; and we get a belt of debris which makes the use of satellites much more complicated.<p>Edit: accidents in quotes
