Three sharp minds. One messy world. In the latest @warontherocks.bsky.social episode, I am joined by @spettyjohn.bsky.social, Justin Logan & Wess Mitchell to talk about hard choices in the sequencing of American strategy. We have some pretty sharp disagreements too

'Spider's Web' warning: The US must prioritize drone defense to avoid Russia’s fate - Breaking Defense CNAS's Stacie Pettyjohn and Molly Campbell argue in this op-ed that Ukraine's clandestine operation should be a wake-up call for the US military and its own base defense.

In @breakingdefense.com Molly Campbell & I argue that Ukraine’s spiderweb drone attack on Russian airbases should be a wake up call for the United States. The DoD needs to make significantly larger investments in CUAS for home & abroad.

From Production Lines to Front Lines The United States needs a different DIB than it has today if it wants to deter and prevail in future great power conflict.

Pleased to release my latest @cnas.bsky.social report on how to revitalize the U.S. defense industrial base so that it can keep pace with modern conflict, deter a future China challenge, and secure U.S. and global interests.

America’s Eroding Airpower Washington must upgrade its fleet of planes, drones, and missiles.

Instead of fixating on cheap drones, the Pentagon should carefully invest in a mix of inexpensive and high-end airpower, argues @spettyjohn.bsky.social.

Oral Histories This Oral History Series has been conducted by the Hoover Institution\'s Wargaming and Crisis Simulation Initiative and features in-depth conversations with leaders, experts, and innovators in wargaming. Through these interviews, the series explores some of the most influential wargames that have shaped U.S. foreign policy and strategic decision-making.

Second, @beccawasser.bsky.social & I were both interviewed as a part of the @hooverinstitution.bsky.social wargaming oral history project.

The announcement that the US Air Force is going to move ahead with the Next Generation Air Dominance fighter (F-47) is welcome because as I note in my Foreign Affairs piece, the US needs a mix of high-end and low-cost AirPower to compete with China.

Happy to share my latest in Foreign Affairs on why the US needs cheap drones & missiles to provide mass & stealthy aircraft to deter China & retain the ability to project power anywhere in the world.

I preview part of my book, which argues that China's turn toward power projection was both inevitable and badly timed (for Beijing).

Build a High-Low Mix to Enhance America’s Warfighting Edge and Deter China The Trump administration can take immediate actions to deter China and reverse negative trends in military power in the Indo-Pacific.

What should the Trump Administration prioritize during its first 100 days? Integrating autonomous systems into the force at scale, backed by warfighting concepts that combine low-cost systems with high-end capabilities. @spettyjohn.bsky.social @carltonhaelig.bsky.social

This is a tremendous feat & something that the US would struggle to do. But it is important to note that not all drones are the same. When I was in Ukraine, one soldier dismissed most of the MOD made FPVs as β€œhamburger drones” that were mass produced, low quality, & minimally capable.

Video Defense expert weighs in on mysterious drone sightings Stacie Pettyjohn, director of the defense program at the think tank Center for a New American Security, discusses the drone sightings, which some officials are calling "a slight overreaction."

I joined ABC news again this morning to talk about the panic over drones in the Northeast.

BLUF: In the words of Tswift: you need to calm down.

The US needs an interagency solution to defend the homeland against small drones, which will require changes to regulations & procedures.

But right now everyone needs to calm down now. Most of the flying objects in the sky are routine civil aviation.

15.12.2024 15:35 β€” πŸ‘ 2    πŸ” 0    πŸ’¬ 0    πŸ“Œ 0

In the United States, no one has the capabilities or authorities to detect & defeat small drones. There are a patchwork of agencies that have responsibilities for this, but no department has been named the clear lead & is equipped for the scale of this growing challenge.

On ABC, I explained that the current drone sightings in the northeast have morphed into public hysteria, but that this is a wakeup call about the growing small drone threat & that the US is not prepared for it. abcnews.go.com/US/video/gro...

Today's Russian missile attack in context: Compared to previous missile campaigns, the current attack demonstrates a similar number of missiles used as during the initial strikes on the power grid.

One of the main trends in the Ukraine war today is capturing adversary drones, repairing them and using them against former owners. Many Russian TG channels post photos and videos of Ukraine-made "Baba Yaga" heavy multirotor drone repairs and use against Ukrainian forces. t.me/milinfolive/...
