I just saw a pic of an old Chinese fighter call the J-7 Fishbed here on the Defense Forum. My question is what is the large needle in the front of the aircraft for? Is it Decoration?:?2 I seen it in the pass on other aircraft.

The fishbed is a mig-21 if i am not wrong and usualy there arent any "decorations" on fighter aircraft other than paint jobs and grafiti, usualy the "needles" are antannae of some sort, communications or sensor related

;)Look at this image - you are talking about component 1 ( 2 and 3 )
this is a Pitot-Static Boom

Front view. In the lower part of the intake cone, barely visible, is the window for the KLEN-54 laser rangefinder/target marker. The short probe protruding from the upper nose is the auxiliary pitot tube, while the longer one includes -front to rear- the main pitot head, the yaw and pitch vanes and a set of aerials related to the radio navigation and landing systems. Note, inside the canopy, the (pneumatically operated) stowed curtain for instrument flying training and the central, rear-viewing, periscope.



A pitot (pronounced /ˈpiːtoʊ/) tube is a pressure measurement instrument used to measure fluid flow velocity. The pitot tube was invented by the French engineer Henri Pitot in the early 1700s[1] and was modified to its modern form in the mid 1800s by French scientist Henry Darcy[2]. It is widely used to determine the airspeed of an aircraft and to measure air and gas velocities in industrial applications.

Ah ok so it something useful then.
I couldn't find the exact picture J-7EB Fishbed - Chinese Air Force - Military Pictures - Air Force Army Navy Missiles Defense
but it does look like the one you showed.
