M777 howitzer and counter-battery/counter-mortar radar.

"The howitzers are especially effective when used in conjunction with counter-artillery radar, the Army officer said, such as the AN/TPQ-36s the US has also sent to Ukraine. The radar systems track incoming projectiles from enemy artillery to calculate the likely spot from which they were fired. With those coordinates, M777 teams can almost immediately direct counterfire on the position."

"But among the list of heavy weapons sent by the US to Ukraine, there’s a little-noticed radar system designed to give soldiers under incoming artillery fire a chance to fight back. The US has sent or is sending two dozen AN/TPQ-36 Firefinder counter-artillery radar systems, which experts say are crucial to turning the tide of battle when paired with artillery weapons like the M777 howitzer that the US is also supplying."

"To counter an artillery attack, soldiers have to know where the artillery is being fired from. Figuring that out — almost instantly — is what the AN/TPQ-36 Firefinder does. The system’s radar spots and tracks incoming artillery, mortars, and rockets and derives a trajectory for the incoming round. With that information, it traces the shot back to the enemy’s firing position and then creates map coordinates that can be used to direct counterfire, according to experts at Fort Sill’s Fires Center of Excellence."

Comments:

* Firefinder useful against enemy artillery, rocket artillery and mortar rounds.

* Data as analyzed and as mentioned can provide precise grid location for counter-fire even before the enemy round being tracked lands!

* M777 can fire Excaliber GPS artillery round for pin-point accuracy.

* M777 towed. The American military authority Trevor Dupuy [an artilleryman] said he preferred the towed weapon in contrast to the self-propelled artillery piece. 

* Firefinder too can be used with the HIMARS rocket artillery system.

Within context see my prior blog entry the Russian rather sophisticated sound-ranging system as also possibly being used in the Ukraine Conflict.
