Let's just say this, TWS isn't used on the Viper according to SME's I've talked to. Especially not on the APG-68 series. The 16 isn't a BVR fighter (withoud MIDS enhancement). If anything the DCS Viper's radar hugely overperforms in detection range, while not being jammable at the same time. The ACM modes seem to underperform on the other hand in terms of acquistion speed and reliability.
