AN/AJB-1 Low Altitude Bombing System

Introduction

The low altitude bombing system was introduced to assist with nuclear weapons delivery. It helps the pilots follow a pre-determined trajectory to delivery nuclear weapons with delivery profiles to assist with escape from the effects of the blast.

Operation

All LABS delivery modes share the pullup timer. The pullup timer is the time set by the pilot to indicate the time taken for the aircraft to fly from a know identification point (IP) to the pullup point.

To calculate the pullup timer use the below formula:

pullup timer = distance from IP to pullup point / ground speed

The ground speed is determined by your release parameters, the indentification point (IP) is chosen to be something that is easy to find and navigate to from the air and near the target area.

LABS (Loft)

The LABS mode is the one of the normal delivery types for the labs. It is intended for lofting nuclear weapons long distances. The release angle is 50 degrees which lofts the weapon a long distance towards the target.

LABS ALT (Over the Shoulder)

The LABS ALT mode is the alternate method for a loft type delivery. It is intended for lofting a nuclear weapon vertically over the target.

The LABS and LABS ALT mode are identical with the exception of the angle of release. Below is a table of release angles:

Mode	Delivery Angle (degree)
LABS	50 (LOFT)
LABS ALT	120 (OVER THE SHOULDER)

Low Altitude Drouge Delivery (LADD)
