The 1973 Old Bailey bombing was a car bomb attack carried out by the Provisional IRA (PIRA) which took place outside the Old Bailey Courthouse on 8 March 1973.
 The attack was carried out by a 10-person ASU from the Provisional IRA Belfast Brigade.
 The unit also exploded a second bomb which went off outside the Ministry of Agriculture in London on the same day at around the same time the bomb at the Old Bailey bomb went off.
 This was the Provisional IRA's first major attack on mainland Britain since The Troubles began back in 1969.
 One British civilian died of a heart attack attributed to the bombing, estimates of the injured range from 180 - 220.
 Two additional bombs were found and defused.
 Nine people from Belfast were convicted six months later for the bombing, and one acquitted for providing information to the police.
Mohammad Daleel (Arabic: محمد دليل), known as Abu Yusuf al-Karrar (Arabic: أبو يوسف الكرار), was a Syrian man who fought for a number of rebel groups during the Syrian Civil War, including the Islamic State.
 On 24 July 2016, he carried out the 2016 Ansbach bombing, killing himself and wounding fifteen people.
 The attack, carried out in retaliation for Germany's role in the Military intervention against ISIL, was the first suicide bombing carried out in Germany.
 German authorities now believe Daleel intended to remotely detonate the Ansbach bomb while filming it and to later commit further terrorist attacks.

The Lewes bomb was a blast-incendiary field expedient explosive device, manufactured by mixing diesel oil and Nobel 808 plastic explosive.
 It was created by Lieutenant Jock Lewes, one of the original members of L Detachment SAS in 1941.
 The SAS needed a combined incendiary and explosive device light enough to be carried by a small group of commandos yet powerful enough to destroy and set fire to aircraft on an enemy airfield.
 Weighing approximately 1 lb , the Lewes Bomb could be carried in quantity by an individual.
The Nakajima Ki-49 "Donryu" (中島 キ-49 呑龍 ) "Storm Dragon" was a twin-engine Japanese bomber aircraft of World War II.
 Despite its official designation as Army Type 100 Heavy Bomber, the requirements of the Ki-49 – to operate unescorted, with heavy defensive armament and armor – restricted it to a small bomb load, initially 1,000 kg (2,200 lb).
A bomb vessel, bomb ship, bomb ketch, or simply bomb was a type of wooden sailing naval ship.
 Its primary armament was not cannons (long guns or carronades)—although bomb vessels carried a few cannons for self-defence—but mortars mounted forward near the bow and elevated to a high angle, and projecting their fire in a ballistic arc.
 Explosive shells (also called "bombs" at the time) or carcasses were employed rather than solid shot.
 Bomb vessels were specialized ships designed for bombarding (hence the name) fixed positions on land.
 In the 20th century, the same role was carried out by battleships, cruisers, destroyers, and the purpose-built World War I- and II-era monitors.
The OFAB-100-120 is a small bomb can be carried on Sukhoi Su-17, Sukhoi Su-25 and Sukhoi Su-30 aircraft.
The Sukhoi Su-25 "Grach" (Russian: Грач ("rook"); NATO reporting name: Frogfoot) is a single-seat, twin-engine jet aircraft developed in the Soviet Union by Sukhoi.
 It was designed to provide close air support for the Soviet Ground Forces.
 The first prototype made its maiden flight on 22 February 1975.
 After testing, the aircraft went into series production in 1978 at Tbilisi in the Georgian Soviet Socialist Republic.
A Butterfly Bomb (or Sprengbombe Dickwandig 2 kg or SD2) was a German 2 kilogram anti-personnel submunition used by the Luftwaffe during the Second World War.
 It was so named because the thin cylindrical metal outer shell which hinged open when the bomblet deployed gave it the superficial appearance of a large butterfly.
 The design was very distinctive and easy to recognise.
 SD2 bomblets were not dropped individually, but were packed into containers holding between 6 and 108 submunitions e.g. the AB 23 SD-2 and AB 250-3 submunition dispensers.
 The SD2 submunitions were released after the container was released from the aircraft and had burst open.
 Because SD2s were always dropped in groups (never individually) the discovery of one unexploded SD2 was a reliable indication that others had been dropped nearby.
 This bomb type was one of the first cluster bombs ever used in combat and it proved to be a highly effective weapon.
 The bomb containers that carried the SD2 bomblets and released them in the air were nicknamed the "Devil's Eggs" by Luftwaffe air and ground crew.
