ATBIP meaning in Governmental ?

Aviation Thermobaric Bomb of Increased Power (ATBIP; Russian: Авиационная вакуумная бомба повышенной мощности, АВБПМ), nicknamed "Father of All Bombs" (FOAB; Russian: "Папа всех бомб", Пвб), is a Russian-designed, bomber-delivered thermobaric weapon.

The bomb is reportedly similar to the US military's GBU-43/B Massive Ordnance Air Blast which is often unofficially called "Mother of All Bombs" derived from its official military acronym "MOAB". This weapon would therefore be the most powerful conventional (non-nuclear) weapon in the world. However, the veracity of Russia's claims concerning the weapon's size and power have been questioned by US defense analysts.

"FOAB" was successfully field-tested in the late evening of 11 September 2007. The new weapon is to replace several smaller types of nuclear bombs in the Russian arsenal.
