Why Does the B-52 Produce So Much Black Smoke?

Welcome back to the Defense Digest channel! In this video, we delve into the iconic B-52 bomber and the mystery behind the plumes of black smoke it produces during takeoff. Despite being in service for over 60 years, the B-52 still uses outdated Pratt & Whitney YJ57-P-3 turbojet engines, which are known for their inefficiency at low speeds and altitudes, resulting in excessive fuel consumption and smoke production.

In this video, we explore the reasons behind the B-52's smoke production, including the type of fuel it uses, JP-8, which is known to produce more smoke compared to other jet fuels. We also discuss the age of the engines and the lack of upgrades to modern turbofan engines, which are more efficient and emit less smoke.

Recently, Rolls-Royce has begun testing F130 turbofan engines for the B-52 as part of the modernization program, sparking a debate on whether the B-52 should be upgraded with newer engines or keep its old ones.
