The US drones crashed near the southern town of Dhobley and the port city of Kismayo.
Somali government officials say they are investigating the exact location of the ruins of the drones. Further details have not yet been released.
Drone strikes in Somalia make the lawless state the sixth country where the US military has used remote-controlled aircraft to conduct such lethal strikes.
The US has now employed drones in Afghanistan, Pakistan, Libya, Iraq and Yemen to launch aerial bombings.
Strategically located in the Horn of Africa, Somalia remains one of the countries generating the highest number of refugees and internally displaced persons in the world.
Somalia has been without a functioning government since 1991, when warlords overthrew former dictator Mohamed Siad Barre.
