• Will Trump’s ‘Big Beautiful’ Defense Spending Last?

    Trump’s signature legislation will push defense spending past $1 trillion, with new funding for innovation and other capabilities. But those investments are at risk of becoming one-off acquisitions without sustained follow-on funding.

  • Hypersonic Weapons and Contemporary Conflicts

    The use of hypersonic weapons in contemporary conflicts marks a turning point in modern warfare as they make defenses vulnerable and expand strategic ambiguity. The US, China and Russia have operational hypersonic weapons. India has recently joined the list by successfully testing a hypersonic missile.

  • The National Security Costs of Trump’s Tariffs

    Looking at the national security ledger, the costs of President Donald Trump’s tariffs are starting to become clearer than the benefits, especially for the U.S. defense industry, critical infrastructure, and relations with partners and allies.

  • What Damage Did the U.S. Do to Iran’s Nuclear Program? Why It’s So Hard to Know

    Disagreements over the damage the U.S. bombing did to Iran’s nuclear facilities are unsurprising. Battle damage assessment –originally called bomb damage assessment –is notoriously difficult, and past wars have featured intense controversies among military and intelligence professionals.

  • MIx Helps Innovators Tackle Challenges in National Security

    Startups and government defense agencies have historically seemed like polar opposites. Startups thrive on speed and risk, while defense agencies are more cautious. Mission Innovation x creates education and research opportunities while facilitating connections between defense agencies and MIT innovators.

  • How Might Israel Attack Iran’s Underground Nuclear Plant? A 2024 Raid in Syria Could e a Template

    One of the key elements of Iran’s nuclear-weapons program is the uranium enrichment plant at Fordow, where about 5,000 centrifuges operate in an underground centrifuge farm 80 meters below ground. Israel may find it difficult to destroy the facility in an aerial attack — it does not have the U.S.-made 30,000lb GBU-57 MOP (massive ordnance penetrator) or the planes to carry this munition. But it may decide to destroy Fordow in a daring ground attack, similar to the one it conducted in Syria on 8 September 2024, in which Israeli commandoes destroyed an underground Syrian missile production facility.

  • China and Rare-Earth Elements: Is Trump Blinking on Tariffs?

    On 2 April 2025, President Trump announced a significant shift in the US trade policy, imposing tariffs on multiple countries, with special emphasis on China. In response, on 4 April 2025, China placed export restrictions on REEs, which are also known as rare metals.

  • BOOM! LIGHTS OUT

    Power generation is the center of gravity for space capabilities, and it is vulnerable to the effects of explosive ordnance, for example, drone delivered bombs.

  • Why Ukraine’s AI Drones Aren’t a Breakthrough Yet

    Machine vision, a form of AI, allows drones to identify and strike targets autonomously. The drones can’t be jammed, and they don’t need continuous monitoring by operators. Despite early hopes, the technology has not yet become a game-changing feature of Ukraine’s battlefield drones. But its time will come.

  • Why U.S. Should Be Worried About Ukrainian Attack on Russian Warplanes

    Audacious — and wildly successful — use of inexpensive drones against superior force can be used anywhere, against anyone.

  • Israel and Iran: An Early Read

    It’s too soon to tell how exactly the current waves of Israeli strikes could transform the region, but one thing is clear: Israel’s actions have fundamentally reshaped the security landscape of the Middle East in the span of less than two years. These two years saw the collapse of Iran’s regional strategy as its two main proxies, Hezbollah and Hamas, have been decimated, while Syria, the linchpin of Iran’s regional aspirations, has changed sides when the country’s Sunni majority removed the pro-Iran Assad regime in December last year.

  • Trump’s Use of the National Guard Against LA Protesters Defies All Precedents

    Unlike his predecessors, Trump has not mobilized the national guard to protect civil rights against a hostile police force. Instead, he appears to be using this as leverage to undermine a political opponent he views as blocking his agenda. Circumventing gubernatorial powers over the national guard in this way has no precedent and heralds the next stage in an extended conflict between the president and the state of California.

  • AI-enabled Control System Helps Autonomous Drones Stay on Target in Uncertain Environments

    An autonomous drone carrying water to help extinguish a wildfire in the Sierra Nevada might encounter swirling Santa Ana winds that threaten to push it off course. Rapidly adapting to these unknown disturbances inflight presents an enormous challenge for the drone’s flight control system.

  • Ukraine’s Drone Attack Offers Fearful Lessons for a Chinese Invasion Force

    Ukraine’s massive drone strike against Russian air bases on 1 June should reverberate across all theaters of conflict. But there is one Western Pacific scenario where it could be very relevant indeed: a Chinese invasion of Taiwan.

  • Ukraine’s Air Force Has Survived. Taiwan’s Almost Certainly Couldn’t

    The Ukrainian air force went to war against invading Russian forces in February 2022 with just 125 combat aircraft concentrated at around a dozen large bases. Given Russia’s overwhelming deep-strike advantage, few observers expected the Ukrainian brigades to survive the first hours of the war. But they did survive. And 38 months later, they’re still surviving—and flying daily air-defense and strike sorties. It has been an incredible feat. Can the equally outgunned Taiwanese air force duplicate it? Almost certainly not.
