<tr><td class='reg1' style="background-color: #FFFFFF;" align='left'>

The Tri-Service system defines the designation of aircraft as follows: 
<div style="margin: auto; text-align: center;">4321-##5</div>

1 - Vehicle type (optional) 
G -- (Glider) -- ex. Waco CG-4A 
H -- (Helicopter) -- ex. AH-64 Apache 
V -- (V/STOL) -- ex. AV-8B Harrier 
Z -- (Lighter than air) -- ex. LZ-129 Hindenburg

2 - Basic Mission 
A -- (Attack) -- ex. A-10 Warthog 
B -- (Bomber) -- ex. B-52 Stratofortress 
C -- (Cargo transport) -- ex. C-5 Galaxy 
E -- (Special electronics) -- E-3 Sentry 
F -- (Fighter) -- ex. F-16 Flacon 
O -- (Observation) -- ex. OA-10 Thunderbolt 
P -- (Maritime patrol) -- ex. P-3 Orion 
R -- (Reconnaissance) 
S -- (Anti-Submarine Warfare) -- ex. S-3 Viking 
T -- (Trainer) -- ex. T-38 Talon 
U -- (Utility) -- ex. U-2 Dragon Lady 
X -- (Experimental/Research) -- ex. X-15

3 - Modified Mission (optional) 
This includes A, C, E, F, O, P, R, S, T, and U from (2) as well as: 
D -- (Drone control) -- ex. DC-130A 
H -- (Search and rescue) -- ex. HH-60 Jayhawk 
K -- (Tanker) -- The "K" comes from Kerosene -- ex. KC-135 Stratotanker 
L -- (Cold weather) -- ex. LC-130H - ski equipped C-130H 
M -- (Multi-Mission) -- ex. MH-53E Sea Dragon 
Q -- (Drone) -- ex. QF-106A - remote control equipped F-106A 
V -- (VIP/staff transport) -- ex. VC-137C - presidential C-137C transport 
W -- (Weather observation) -- ex. WC-130J - weather reconn. of C-130J

4 - Status (optional) 
G -- (Permanently grounded) -- ex. GF-101B 
J -- (Special test - temporary) -- ex. JB-26C 
N -- (Special test - permanent) -- ex. N-9M Flying Wing 
X -- (Experimental) -- ex. XF-89 - lead to F-89 Scorpion 
Y -- (Prototype) -- ex. YF-17 Cobra 
Z -- (Planning)

5 - Variant 
Specifies a particular variant of an aircraft -- &nbsp;&nbsp;&nbsp; ex. F-16A - F-16B, F-16C - F-16D Falcon

A few outliers to these standards would be outdated aircraft and exceptional aircraft, such as: 
ER -- (Earth Resources) -- ex. ER-2 
SR -- (Strategic Reconnaissance) -- ex. SR-71 Blackbird 
TR -- (Tactical Reconnaissance) -- ex. TR-1 
P -- (Pursuit) -- ex. P-51 Mustang (discontinued) 
L -- (Liaison) -- ex. L-19 Bird Dog (discontinued)

So a completely made-up yet possible aircraft would be the XFBG-109C, which would be: 
An experimental glider-bomber modified for a fighter mission, the third variant of the 109th glider aircraft.
