Dassault Mirage IV Supersonic Bomber

Dassault Mirage IV is a French jet-propelled supersonic strategic bomber and deep-reconnaissance aircraft. For many years it was vital wing of the nuclear triad of the Force de Frappe, France’s nuclear deterrent striking force.

Dassault Mirage IV
is similar in design layout to the Mirage fighters, featuring a tailless delta wing and a single square-topped vertical fin. It has two SNECMA Atar turbojets in the rear fuselage, with air intakes on both sides of the fuselage that had intake half-cone shock diffusers, known as souris.

The Mirage IV can reach high supersonic speeds: the aircraft is redlined at Mach 2.2 at altitude because of airframe temperature restrictions, although it is capable of higher speeds. The aircraft has 14,000 liters (3,700 gal (US)) of internal fuel, and its engines are quite thirsty, especially in afterburner.

The Mirage IV has two pylons under each wing, with the inboard pylons being normally used for large drop tanks of 2,500 liter (660 gal (US)) capacity. The outer pylons carry ECM and chaff/flare dispenser pods to supplement the internal jamming and countermeasures systems.
