This 4-view drawing of the Northrop
SM-62 Snark was scanned from page 21 of my purchased edition of the December 1957
American Modeler magazine. It is another example of Walter Jefferies' fine
Northrop SM-62 Snark
Scale Presentations by Walter M. Jefferies, Jr.
First U.S guided missile with intercontinental range, the tailless turbojet powered
weapon cruises at high sub-sonic speeds. With nuclear warhead and range of strategic
jet bombers, its range can be extended by addition of large pylon-mounted, underwing
auxiliary fuel tanks. Combination ailerons and elevators, called elevons, are mounted
on trailing edge of wing about mid-span. Thin wing is swept back 45°. Parabrake
to aid in recovery of missile is housed in compartment above jet exhaust. Originally
powered by an Allison J-71 turbo-jet, Snark now has a Pratt and Whitney J-57. Take-off
is aided by two booster rockets mounted each side of fuselage just ahead of turbo-jet
intake. Rocket units jettison after burning out.

The AMA Plans Service offers a
full-size version of many of the plans show here at a very reasonable cost. They
will scale the plans any size for you. It is always best to buy printed plans because
my scanner versions often have distortions that can cause parts to fit poorly. Purchasing
plans also help to support the operation of the
Academy of Model Aeronautics - the #1
advocate for model aviation throughout the world. If the AMA no longer has this
plan on file, I will be glad to send you my higher resolution version.
