The Weekly Preflight: 5 Things I'm Watching | Week of April 20, 2026
Think of this as your weekly strategic weather report
Five things to watch and what could break next in defense tech and geopolitics. Just the pressure points and strategic tells most likely to shape the next seven days.

By the way, if you want to understand how I build my OSINT dashboard, I wrote about my workflow here:
Let’s jump in:
1. The Touska seizure
USS Spruance, an Arleigh Burke-class (Flight IIA) Aegis guided missile destroyer, disabled the sanctioned Iranian cargo vessel Touska in the Gulf of Oman early this morning, firing its 5-inch MK 45 gun directly into the ship’s engine room before US Marines took custody of the vessel. I’ve seen the video of the firing; the US Navy warned the Touska crew to evacuate the engine room before firing.
Iran responded with drone strikes against US naval assets and called it “armed piracy.” Their Foreign Minister says it violates ceasefire terms.
You can watch the Marines fast-rope onto the Touska here:
The Spruance action is the first direct kinetic seizure of an Iranian vessel in this conflict.
What I’m watching: Whether Iranian drone strikes caused any confirmed damage to US naval assets. A miss is one outcome. Watch CENTCOM statements closely. If they’re vague about damage, assume there’s something they’re not ready to disclose yet.
I’m also watching the insurance markets: if Lloyd’s of London war risk premiums spike on Gulf of Oman transits, that’s confirmation the commercial shipping world thinks this just got more dangerous. As part of my workflow, I scan the 10-day review of reported container shipping casualties on Lloyd’s. If you’d like to do the same just remember there’s a 24-hour delay for updates.
2. North Korea reminds everyone that they still exist
Kim Jong Un personally supervised a ballistic missile test this weekend.
North Korea has a long and documented history of running provocations during periods of US strategic distraction, and right now the US is as distracted as it’s been in decades, with the administration’s diplomatic bandwidth consumed entirely by the Iran file.
Kim reads the room. His ego requires that world leaders notice him. A test under direct leadership supervision, announced through state media, on the weekend the Spruance fired into an Iranian ship is Kim making sure the world still remembers that he’s a threat.
The specific detail worth noting: the missiles are described as “upgraded” which may telegraph a capability demonstration. Upgraded from what, and in which direction, matters enormously. Longer range? Maneuverable reentry vehicles? Hypersonic glide?
Those are different threat profiles with different implications for South Korea, Japan, and US forces at Yokosuka, where USS George Washington is currently in port.
What I’m watching: Additional DPRK launch activity in the 48-72 hour window. Kim rarely stops at one test when the strategic environment is this favorable for provocation. Also watch for South Korean and Japanese government statements; their public tone will tell you more about what the intelligence community is actually seeing than any USINDOPACOM (United States Indo-Pacific Command) press conference will.
3. Ukraine just rewrote naval drone doctrine (again)
Ukraine’s Unmanned Systems Forces executed the first-ever intercept of a Russian Shahed drone using a drone launched from an unmanned surface vessel. Yup. A USV, operating in a contested maritime environment, launched an aerial interceptor that successfully killed an incoming drone.
