TASK UNIT 5, TIMING
Objectives
TU-5 had two principal objectives--the first, to provide a remote control system that would arm and fire a surface-detonated device with a high
degree of reliability; the second, to supply experimenters with an accurate
sequence of timing signals related to zero time for the purpose of starting
or stopping their equipment on either airdrop or ground operation.
Closely associated with these objectives were six other projects:
1. To determine the time of burst with respect to WWVH.
2. To furnish personnel as members of the firing party.
3,
To install a system ceopable of monitoring vital information from
zero site to the control station.
4, To provide signals to experimenters for airdrop tests.
5. To provide voice-time announcements synchronized to the timing
system.
6.
To provide a shipboard control station for remote operation of the
Bikini timing system,

Procedure
Early in August 1955, preliminary planning for a timing system to
meet anticipated Redwing requirements was begun. As planning progressed,
station locations and details of the timing system were worked out.
The equipment was assembled and operationally tested under simulated
field conditions in the Las Vegas laboratory prior to shipment to the FA.
Shipment of equipment to the FA began in December 1955 ard continued
through April 1956.
Early in February, a group of field personnel was sent to the FA to
start field installation of the timing and firing system. As equipment continued to arrive, additional personnel were dispatched. A total of 55 tons
of timing system equipment was shipped to the FA.
Installation of all equip-
ment was completed by May 1, 1956.
The following control and distribution stations were used in the Bikini
