For 56 years, they watched. The Defense Support Program's satellites scanned the planet from high orbit for the infrared flash of missile launches, giving the United States and its allies precious minutes of warning through the Cold War, Desert Storm and beyond. This fall, the U.S. Space Force retired the final two DSP satellites. After one last exercise, they were boosted into a graveyard orbit, and their 56-year watch came to an end.

Much of that story began right here. The first DSP satellite left Launch Complex 40 on a Titan IIIC on November 6, 1970. Of the 23 DSP spacecraft launched, all but one departed from the Cape Canaveral area, riding Titan IIIC, Titan 34D, Titan IV and finally the Delta IV Heavy, which carried DSP-23 from Space Launch Complex 37 on November 11, 2007. The lone exception, DSP-16, flew aboard Space Shuttle Atlantis in 1991. During Desert Storm, DSP detected Scud launches and warned coalition forces and civilians. Its infrared eyes could even spot forest fires and volcanic eruptions.

This shirt celebrates the Defense Support Program and the people who kept it watching over us. Like every Cape Kennedy Clothing design, it includes a QR code that links to the real history behind it.

Fit & Sizing:

Our shirts run roomy on purpose. They are cut in the authentic vintage camp-collar style with 6 to 9 inches of room through the chest, so they drape and breathe rather than cling.

  • Order your usual size for the classic relaxed look.
  • Order one size down for a closer, modern fit, or if you fall between two sizes.
  • Pre-order shirts are final sale, so measure first.
  • Planning to machine-dry on heat? Size up. A hot dryer can shrink a cotton/rayon shirt by up to a full size.
  • To be certain, lay a shirt you already own flat, measure straight across the chest and double that number, then match it to the Shirt Chest column in the Size Guide.

Ordering & Delivery:

  • Pre-orders: open now. The close date will be announced.
  • Design: in progress. We'll reveal it on this page.
  • Shipping: we'll share a ship date once production is confirmed.
  • Final sale: pre-orders can't be returned, exchanged or cancelled. Damaged or defective shirts are always replaced.
