Behind an unmarked office building near Los Angeles International Airport, there is a row of hypersonic missiles without warheads, about the size of small drainage pipes. On February 6th, a disguised truck transported one of the hypersonic missiles to New Mexico for test firing by the US Air Force. Such activities used to be common in the El Segundo area of Los Angeles, which was once a military space center. Later, the Cold War ended and most of the weapons business on the West Coast of the United States also came to an end. Now it's back: Castellion Corporation, which manufactures missiles, was founded in Los Angeles in 2022. Los Angeles is not the only place to awaken the deeply buried 'warrior spirit' of the past, Silicon Valley is also doing so. In the early stages of development in the mid-20th century, Silicon Valley manufactured reconnaissance equipment for spy planes and semiconductors for missiles. But later, pacifists took over Silicon Valley, and for decades, 'defense' became a dirty word. Just two years ago, Castellion was unable to open a bank account in Silicon Valley because manufacturing weapons was a shame. Afterwards, some developments made Silicon Valley tense its muscles, one of which was the Ukrainian war. However, perhaps the most tempting thing is the sweet aroma of economic success. SpaceX has become the most valuable private company in the United States with a valuation of $350 billion. Palantir, which provides software to Western military and spy agencies, has a market value of over $250 billion, which is higher than the combined market value of three traditional defense contractors, Lockheed Martin, Northrop Grumman, and General Dynamics. Anduril Corporation is a young company that manufactures automated weapons and is currently raising $2.5 billion at a valuation of $28 billion. A large amount of investment has been pouring into small start-ups that produce military equipment for land, sea, air, and space. The data collection agency "Project Proposal" said that in the past two years, the value of such transactions in the United States has increased by more than one-third, reaching nearly $40 billion. During this period, overall venture capital has declined. In history, venture capitalists have been reluctant to support the hardware industry, especially hardware industries like defense that can consume a large amount of capital. This situation is changing. Many people in Silicon Valley are also changing their worldview, abandoning the liberal spirit that has prevailed in recent decades and instead supporting a patriotism that praises the military strength of the United States. Silicon Valley's renewed interest in military hardware reflects a shift in the combat landscape displayed on the Ukrainian battlefield: small arms, especially drones, have become a supplement to heavy weapons, sometimes even replacing them. This leaves an opportunity for rising stars who can manufacture smarter or cheaper drones. Drones driven by advanced artificial intelligence systems have become popular. Frugality has also become popular. Taking Castellion as an example, for missile systems, it uses automotive grade chips that cost only a few hundred dollars instead of expensive space grade chips. It manufactures its own rocket engines to reduce costs. Space exploration technology companies are able to send satellites into low Earth orbit at a low cost, allowing satellites to monitor the Earth, making space an increasingly affordable part of battlefield technology. Like many defense technologies supported by Silicon Valley, these technologies can also be used for civilian purposes, thereby increasing their revenue potential. The resurgence of the "warrior spirit" is also changing the relationship between Silicon Valley and the US government. The new book "Tech Republic" co authored by Alex Capp, CEO of Palantir, is about to be published, which calls for Silicon Valley to collaborate with Uncle Sam on military projects. People like Kapu do not support environmental and social causes, but instead make patriotism a new corporate goal. This concept will be of interest to many people in the Trump administration.
