Danish F-16s are F-16AM Block 20s (Originally Block 1/5/10/15, which where all upgraded in the Mid Life Upgrade program in the early 2000s to bring them up on par with the F-16C Block 50) They have been continuously upgraded to this day. They currently field JHMCS, along with locally made missile launch detection pylons (Terma) with extra countermeasure slots. They might not have the best radar and lack stealth, but together with solid avionics, better defensive systems, datalink and good intel, It'll be able to do very well in the right hands. Thanks to those upgraded avionics, will the Ukrainians now be able to actually utilize their HARM missiles and JDAMS properly, along with AIM-120 AMRAAM's. The only thing holding back those F-16s are simply metal fatigue in the airframes.
