NASA Forgot the Largest Rocket Booster It Built - in the 1960s.

NASA's Space Launch System Booster Thunders During Successful Ground Test

"The largest, most powerful rocket booster ever built successfully fired up Wednesday ..."

Aerojet, Wikipedia

"Between Sept. 25, 1965 and June 17, 1967, three static test firings were done. SL-1 was fired at night, and the flame was clearly visible from Miami 50 km away, producing over 3 million pounds of thrust. SL-2 was fired with similar success and relatively uneventful. SL-3, the third and what would be the final test rocket, used a partially submerged nozzle and produced 2,670,000 kgf thrust, making it the largest solid-fuel rocket ever."

Keith's note: That picture shows 5.88 million pounds of good old 1960s Aerojet rocket thrust folks (larger image) compared with only 3.6 million pounds of 2015 Orbital ATK thrust. Funny how NASA has forgotten the amazing things it once paid Aerojet to do back in the day. Indeed it has been thumping this incorrect "most powerful rocket booster" mantra for weeks.
