"Valkyrie" Multiple Missile Launch System.
A compact weapon pod for aircraft. Allows for many missiles to be stored in a compact configuration, but is heavy and causes immense drag.

Configuration 1: 5x AA-01R1 short-range passive infrared air-to-air missiles. Devastating in a dogfight and can lock onto surface targets, but is less effective than a dedicated air-to-surface missile.
Configuration 2: 4x AS-01R1 short-range electro-optical air-to-surface missiles. Great against large numbers of light targets, and can take on ships with enough of them.
Configuration 3: 16x AA-03 short-range passive infrared air-to-air missiles. Intended for overwhelming a target's defenses. The missile is too small for pylons and can only be used in weapon pods such as the Valkyrie MMLS. Although intended primarily for air-to-air, it can lock onto and damage ground targets, but won't sink a ship.
Configuration 4: 16x rockets
More rockets than the built-in rocket pod at the cost of incredible drag.
Configuration 5: 25mm Metal Storm weapon system. The 36-barrel Metal Storm prototype in real life can fire at one million rounds per minute, but this fire rate is not possible in SimplePlanes. It uses electricity to fire caseless cartridges stacked together in multiple barrels.
Configuration 6: 50mm Metal Storm weapon system.
