• CV47/Al6-13 20/EMS/wn

' .

&• Performance .. The crew continued to perform their duties during flight operations and replenishment in an outstanding manner•

b. Casualties - There was one fatality during the period• MURRAY, F.J., ETC, 222 91 28, USNR, died from Embolism D•9•C• Cerebral• ~IEUTENANT HIIGEL, G.E., 304262, received a low back sprain and contu§ions when the AD-4N in which he was flying failed to gain enough speed an! want into the sea during launching. _,,t'"rEUTENANT (Junior grade) 'l:Hm~pgcN, M...E., 390065, received mild qpntusion of the left ·shoulder when the F4U he was flying went into the sea.

\ltzy:lJTENA.NT FREES1 N.w., Jx., 125282, received a sprained back when the AD-4W he was flying went_ into :the sea• One enlisted man, MORELLI, F.G., 949 93 50, USN, received a fracture of the right arm from a fall to tha hangar deck from the flight deck. Minor injuries consisting of lacerations, contusions, ate•, while numerous, do not show any appreciable increase in rata.

Part VI - Doctrine and Operating Procedures

&• Jet Operations -At the request of Commander Carrier Division ONE, VF-111 and VF-112, the jet squadrons attached to this vessel, have prepared a pamphlet on F9F-2 operating procedures during the Korean Campaign. This pamphlet representing over six months of combat operating experience, is believed to contain much information of value to new squadrons and ships operating the F9F-2 and is attached herewith as encloste (1).

b. Mixed Ordnance Loads on Aircraft Wing Stations

(1) Mixed ordnance loads on the wingo of both I< -4B and AD-4 have recently been ordered for certain types of missions. Such mixed ordnance wing loadings as bombs and rockets are recommended against under the present type of operations for the following reasons:

(a) Bomb and rocket attacks vary widely in nature. Rocket attacks are often carried out at very low altitude due to the nature of the target, terrain and the close range required to insure accuracY• Safe pullout alti­tude is considerably lower than that for the 100 lb. G.P. and 220 or 260 lb•. !rag. bombs.

(b) The wing station bomb and rocket selector arrangement offers an easy setting of switches which permits improper selection• The automatic selector switch was designed for sequence release of a single type of ordnance•

'(c) In addition to simple improper selection resulting in the wrong type of ordnance being released, the type of attack may result in danger to the aircraft through release of a bomb while making a low altitude pullout attack intended for rocket release.

(2) It is considered desirable in many eases to have a wide variety of ordnance available but it is believed wise to incorporate this variety between

-4-

. .

aircraft rather than on each aircraf't until a more adaptable -wing station se­lector system is provided in the a:ircratt. The present selector system arr:l incorporation of variety between aircraft are considered adequate for the present, however• · ~

O• Rear=ToJ1M TOJ Bars tor Tricycle Jet Aircraft\\

(l) Coml.irl'ac letter serial l0/01450 of 19 Docs~ or 1950 requested further information regarding the unsuitability of rear ing t011 bars• The presently used rear-towing be.rs are a makeshift design which have the following undesirable featuress

(a) Attschmsnt to tha tail skag places Ulldue side loads upon a part not designed to take them•

(b) The tsil skag attschmsnt is necessarily a fairly loose fit which permits oscillation to build up in towing; sometimes so severe the air­craft must be stopped.

(c) The aircraft tail skag and towing bar do not ride smoothly over deck projections, such as tie down channels-, barriers and cross-deck peaiants. In slowing the F9F, the tail tends to drive down onto the deck•

(d) Only shallow turns are possible with the present nakoshift tow bars.

(e) The towbars are rather clumsy to handle and, without suitable rollers on the short leg7 often catch and tear the nylon jet barriers.

(f) The towbars, like those for conventional earrier aircraft, do not permit towing into the final spot; a desirable feature for new designs for carrier deck toning systems.

d • Mar Met.Qs!d Air Operations

(1) Whenever air opsrations ere conducted by the BABER Method, it is recommended that a course and speed intention signal be given thirty minutes in advance of the scheduled operation•
