Taking into account the improvement of proficiency and the gradual stabilization of the system during the construction of the ship, the follow-up 055 may not need 36 months to serve, so the 055 destroyer No. 104 is likely to serve in a short period of time.I checked wikipedia and found 104 was launched in May 9, 2020. Then it's only 21 months since it was launched.
The previous four Type 055s spent 30, 34, 34, 26 months outfitting and trialing before entering service. For 106 the #5, if it would be commissioned in March, then there's a 31 months interval.
So 104 may much likely not be commissioned within six months.
