Jordan says it has carried out 56 air strikes in three days on Islamic State logistics sites and hideouts.
"We achieved what we aimed at," Air Force chief Gen Mansour al-Jbour said. Jordan intensified its strikes after captured pilot Moaz al-Kasasbeh was shown being burned alive by IS.
Jordan has carried out nearly 20% of all sorties by the US-led coalition against IS in Syria so far, Gen Jbour said, adding: "We are determined to wipe them from the face of the Earth."
IS seized control of large areas of Iraq and Syria last year, prompting hundreds of raids by coalition war planes.
The focus of Jordan's air strikes is reported to be Raqqa, the IS stronghold in Syria, but no specifics were given.
Gen Jbour said the strikes had degraded nearly 20% of the militants' capabilities.
Jordan announced it conducted dozens of air strikes on the Isis (Islamic State) group that murdered one of its pilots, as part of an international assault Washington says is bearing fruit.
Air Force chief Major General Mansour al-Jobour told reporters the kingdom had launched 56 air raids on Isis since Thursday.
"On the first day of the campaign to avenge our airman Maaz al-Kassasbeh, 19 targets were destroyed, including training camps and equipment," he said, reading from a prepared text.
Jordan has vowed to crush Isis after the jihadists burned alive Kassasbeh, who was captured in December when his F-16 warplane went down in Syria.
Eighteen more targets including ammunition and fuel depots and logistics centres were hit on Friday.
"So far, the campaign has destroyed 20 per cent of the fighting capabilities of Daesh," he said using another name for Isis which controls swathes of both Syria and Iraq.
Jordan is part of the US-led coalition of Arab and Western countries that has been carrying out air strikes against Isis since September.
State media reported that a squadron of United Arab Emirates F-16 fighter jets arrived Sunday in Jordan escorted by pilots and technicians.
C-17 transporters and refuelling planes were part of the squadron sent to on the orders of Abu Dhabi Crown Prince Mohammed bin Zayed al-Nahayan, the Petra news agency said.
US Secretary of State John Kerry said the aerial campaign on Isis in Iraq and Syria was beginning to win back territory seized by the jihadists and deprive the group of key funds.
There have been 2,000 air strikes on IS since the coalition's formation in August, Kerry told the Munich Security Conference.
The air war had helped to retake some 700 square kilometres of territory, or "one-fifth of the area they had in their control," he said.
The top US diplomat did not specify whether the regained territory was in Iraq or Syria.
But he added the coalition had "deprived the militants of the use of 200 oil and gas facilities... disrupted their command structure... squeezed its finance and dispersed its personnel."
- 'Turning point' -
Jordan's Foreign Minister Nasser Judeh said that while the bombing campaign had "degraded" Isis capability, the group was still in control of "vast territory".
"They still have access to Syria's cash and funds. They have access to weaponry. They're not gone as a threat yet," Judeh told ABC television.
Interior Minister Hussein Majali said in remarks published on Saturday that Kassasbeh's gruesome murder by Isis was a "turning point" in the kingdom's fight against extremism.
"The day of the hero, martyr pilot's assassination is a turning point in Jordan's history in order to face this horrific crime that was committed by the cowardly terrorist organisation," he said.
Jobour said more than 7,000 Isis militants had been killed since Jordan began participating in coalition air strikes.
Following Jordan's intensified sorties, the group claimed US hostage Kayla Jean Mueller had been buried alive under rubble in its self-proclaimed capital of Raqa in Syria.
Mueller's parents said they were hopeful the 26-year-old aid worker was still alive and appealed to Isis to contact them in order to ensure her safe return.
On Sunday, US Secretary of Homeland Security Jeh Johnson said Washington was seeking clarification on Mueller's fate.
"We're learning as much as we can as quickly as we can about Ms. Mueller's situation," he told CNN. "Our thoughts, our prayers are with her family right now."
Also on Sunday, the Lebanese army received a shipment of US weapons worth $25 million to help fight jihadists who have staged incursions from Syria.
Gen Jbour says Jordan's plan of destroying Islamic State is being carried out
A video of Lt Kasasbeh, 26, being burned alive in a cage, was posted online by IS earlier this week.
He was captured by the militants in December after his F-16 fighter jet crashed in Syria. The video is believed to have been filmed on 3 January.
Jordan had offered to swap Sajida al-Rishawi, a failed female suicide bomber, for the captured pilot. Jordan executed Rishawi and another convicted al-Qaeda operative on Wednesday.
