In the official announcement on May 20, it was suggested that the water depth is 6~9m.
It means 250kg of high-performance explosive, and when calculating the actual amount of tnt explosion, the RE coefficient must be calculated according to its composition.

As noted earlier, Iran has a variety of torpedoes, including wake homing designs. Some can be used at long ranges of 4,000 to 5,000 meters. Others can equip remotely ontrolled small craft or suicide vessels. Some sources also report it has a range of much longer range homing torpedoes, although experts serious question such reports:

Iran announces serial production of YT-534 UW1 'Valfajr' torpedo
Iran on 13OCT15 announced serial production of the the Marine Industries Organization YT-534 UW1 Valfajr ("Dawn") anti-surface torpedo.
According to MODAFL, this latest variant of the YT-534 (North Korean export designation for PT-97W) is "mostly utilized in the submarines," features "short pre-launch preparation time" and "detects the target with radars and sonar."
This variant with "U" in the designation appears to provide the Ghadr-class midget submarine with capability to launch the YT-534 type wake homing torpedo. Indeed the video provided below appears to depict an IRIN Ghadr-class test-launching a YT-534 UW1 Valfajr torpedo.
The Valfajr torpedo was previously announced in 2011 with specifications that included a 220 kg warhead.
