At least as far as 5th January 2007, when H6K took its maiden flight. Not sure if there is any other version without tail gun turret prior to H6K.Does anybody know when the H-6 deleted the tail turret like the one found on the Tu-16?

There are older pre-2000s variants without the turret such as the H-6H missile carrier, but that one had some sensors above and below the gunner station instead of the more modern H-6K,J,N APU.At least as far as 5th January 2007, when H6K took its maiden flight. Not sure if there is any other version without tail gun turret prior to H6K.

Hi,A H-6J seen flying with what looks to be YJ-12(?) missiles. Posted by @欧阳振我86468 on Weibo.

Prototype with max payload and bomb-bay open

现况:我军国产战略轰炸机发射反舰巡航导弹只能外挂不能内埋
研究:内埋6联装旋转挂架
空心转轴长5m外径0.5m壁厚20mm,材料铸造合金钢:图1
挂耳距离928mm,导弹折叠弹翼(文中省略):图2、图3
发射用时1~1.5s,旋转用时2s(加减速各0.5s、最大角速度维持1s),连发间隔<3.5s
投弹方案一:图4、图5
逆时针旋转依次投放,旋转角度为60°→60°→60°→60°→60°
最大角速度40°/s
投弹方案二:图6、图7
对称投放,旋转角度为180°→60°→180°→60°→180°
最大角速度120°/s
比较:图8~图11
方案二振幅、加速度更小
Current Status: Our military's domestically produced strategic bomber can only launch anti-ship cruise missiles externally; it cannot carry them internally.
Research: Internally mounted six-cell rotary launcher.
The hollow rotating shaft is 5m long, with an outer diameter of 0.5m and a wall thickness of 20mm. Material: Cast alloy steel. (Figure 1)
The distance between hanging lugs is 928mm. Missile features folded wings (omitted in the text). (Figures 2, 3)
Launch time: 1–1.5s. Rotation time: 2s (0.5s each for acceleration and deceleration, 1s at maximum angular velocity). Salvo interval: < 3.5s.
Bombing Scheme 1: (Figures 4, 5)
Release sequentially via counterclockwise rotation, with rotation angles: 60°→60°→60°→60°→60°
Maximum angular velocity: 40°/s
Bombing Scheme 2: (Figures 6, 7)
Symmetrical release, with rotation angles: 180°→60°→180°→60°→180°
Maximum angular velocity: 120°/s
Comparison: Figure 8 - Figure 11
Scheme 2 exhibits smaller amplitude and acceleration.
