The Ripple concept, which used ablation to achieve fusion using very little fission, was and still is by far the cleanest design. Unlike previous clean bombs, which were clean simply by replacing the uranium-238 tamper with lead, Ripple was inherently clean. The fission sparkplug was replaced by a large deuterium-tritium gas core, surrounded by a tamper-like lithium deuteride shell. It is assumed that thin concentric shells of a high-Z material like lead, driven by the small [[Kinglet (nuclear primary)|Kinglet primary]] allowed propagated sustained shockwaves to the core, sustaining the thermonuclear burn and giving the device its name. The design was influenced by the nascent field of [[inertial confinement fusion]]. Ripple was also extremely efficient; plans for a 15 kt/kg were made during [[Operation Dominic]]. Shot Androscoggin featured a proof-of-concept Ripple design, resulting in a 63-kiloton fizzle (significantly lower than the predicted 15 megatons). It was repeated in shot Housatonic, which featured a 9.96 megaton explosion that was reportedly >99.9% fusion.<ref name="q320">{{cite journal |last=Grams |first=Jon |date=2021-06-06 |title=Ripple: An Investigation of the World's Most Advanced High-Yield Thermonuclear Weapon Design |url=https://muse.jhu.edu/article/794729/pdf |journal=Journal of Cold War Studies |publisher=The MIT Press |volume=23 |issue=2 |pages=133–161 |issn=1531-3298 |access-date=2025-04-07}}</ref>
