You have to give it to the Chinese military. Whilst they're investing in loads of new tech (J-20, T-96/99, J-31, AWACS etc), the relatively modest upgrades to the H-6K (DK-30's, SatNav, EW suite and ALCM) has given them a dramatic and very cost effective boast in capability without the years and expense of R&D for a totally new platform or strain on their existing maintenance and supply chain infrastructure.
This is much like the USAF's constant upgrades of the B-52, which when operating in uncontested airspace is one of the most cost-effective launch platforms and bomb trucks available.
I hadn't noticed the FLIR ball under the chin of the H-6 previous, does anyone know of this confers a smart bomb (sino-JDAM) targeting on the H-6K or is it simply to provide a true all weather capability?

One of the cardinal rules of military procurement is to not let perfect be the enemy of the good (especially since good has a lot less risk).
