pressure head in the bulk drum to transfer H-70 to the
charging unit. The charging unit is 75 inches (1900 mm) long
by 36 inches (900 mm) wide by 92 inches (2340 mm) high and
weighs approximately 475 pounds (216 kg). An F-16 tactical
wing is expected to use approximately 100 gallons (380 L) of
H-70 per 20,000 flight hours with an additional minimum of 150
gallons (570 L) held in reserve to handle deployment/safety
General Design Considerations
a) H-70 carries the compatibility group designation
of Group C.
b) Separate H-70 fuel storage and liquid/gaseous
oxygen storage in accordance with AFMAN 91-201. Locate the
facility a minimum of 50 feet (15 m) from aboveground
explosive storage in accordance with AFMAN 91-201.
c) Locate the facility a minimum of 100 feet (30 m)
from public highways; civilian or government living areas;
public facilities such as schools, churches, clubs, sewage
treatment plants; or rivers, lakes, or streams because of bio-
d) Segregate the servicing and storage facility from
large population concentrations within the confines of a
military installation and subject to the criteria stated
e) Store 55-gallon (210 L) drums of hydrazine in
facilities no less than 80 feet (24 m) apart. The spacing is
also subject to the other criteria stated in this section.
This criterion is limited to ten 55-gallon (210 L) drums and
20 EPU tanks (provided the tanks are stored inside an approved
f) Refer to Army Corps of Engineers TO-42B1-1-18 and
TO-42B1-1-18S-1 for additional information.
Construction Concepts. Provide the H-70 facility
with space for tank servicing, storage, and personnel hygiene.
