the detent. A spring-loaded firing contact (fig. 2-20) is
located in the end of each tube.
The   principles   of   operation   for   the   2.75-inch
launcher   are   basically   the   same   as   the   5.0-inch
launcher.  The  2.75-inch  launcher  can  be  loaded  with
less  than  7  or  19  rockets  when  tactical  requirements
exist. However, you should refer to the specific tactical
manual  and  aircraft-loading  manual.  Also,  since  the
rockets are fired in a definite sequence, the rockets must
be   loaded   into   the   launcher   tubes   in   the   proper
sequence.
Airborne
rocket
loading
procedures,
including electrical test procedures, are covered later in
this manual.
