Lockheed–Aerojet Rocketdyne blocked (2020–2022)
Lockheed agreed to buy Aerojet Rocketdyne, a top maker of rocket motors, for $4.4 billion. The Federal Trade Commission sued to block it, arguing Lockheed could starve rival missile makers of a key input. Lockheed dropped the deal.
Lockheed terminated the purchase in February 2022 and paid no breakup fee to regulators.
L3Harris later bought Aerojet Rocketdyne for $4.7 billion, cleared in 2023 because L3Harris was not a competing missile prime.
It shows the exact worry regulators may raise here: a prime buying a supplier that also feeds its competitors.
