"Beyond this major upgrade, Blue Origin also announced other modifications intended to improve the overall performance of the rocket: Increasing the thrust of a BE-4 engine from current levels, 550,000 pounds (lbf), to 640,000 pounds Increasing thrust of BE-3U upper stage engines from 320,000 pounds to 400,000 pounds Use of super-cooled cryogenic propellants Development of a reusable payload fairing Higher performing and more reusable heat shield to reduce refurbishment time Lower-cost tank design (presumably for the upper stage, which is not reusable)"
"Blue Origin said that both its 7×2 and 9×4 variants will fly concurrently. This, the company said, will give "customers more launch options for their missions, including mega-constellations, lunar and deep space exploration, and national security imperatives such as Golden Dome.""
"The increased pace of announcements and execution appears to be part of a plan by the company's chief executive, Dave Limp, to get Blue Origin moving more quickly. Hired by Jeff Bezos from Amazon, Limp has shaken up Blue Origin's culture, which had stagnated under former CEO Bob Smith despite Bezos showering the company with billions of dollars annually. In his nearly two years on the job, Limp has focused on expanding Blue Origin's manufacturing capabilities and pushed for tighter execution on more rigorous deadlines. Before, it would have been possible to dismiss the rocket plans unveiled Thursday as distant goals. But last week's launch and subsequent landing of the New Glenn rocket suggest the company is finally breaking out."
Blue Origin will increase BE-4 engine thrust from 550,000 lbf to 640,000 lbf and BE-3U upper stage thrust from 320,000 lbf to 400,000 lbf. The company will use super-cooled cryogenic propellants, develop a reusable payload fairing, deploy a higher-performing reusable heat shield to reduce refurbishment time, and implement a lower-cost upper-stage tank design. Both 7×2 and 9×4 New Glenn variants will fly concurrently, providing more launch options for mega-constellations, lunar and deep space missions, and national-security needs. Blue Origin is developing a full-scale deployable aerobrake. CEO Dave Limp has prioritized manufacturing expansion and stricter execution, evidenced by a recent New Glenn launch and landing.
