An airport spokesman said police officers surrounded the aircraft after it landed at 17:15 GMT.
A blast was heard coming from the Dartford area at about 16:40 and was also felt across the county, according to posts on Twitter.
The airport spokesman said surrounding the plane was standard procedure when communication had been lost with an aircraft.
He said officers were later stood down and the plane was continuing its journey.
Tweetdeck founder Iain Dodsworth tweeted audio of the blast, which he described as an "explosion".
'Supersonic speed'
An RAF spokesman said: "Typhoon aircraft were launched this afternoon from RAF Coningsby to intercept a civilian aircraft south of London which was causing concern to air traffic control authorities.
"The aircraft was safely escorted to London Stansted.
"To fulfil their quick reaction role the Typhoons were cleared to travel at supersonic speed, any noise disturbance as a result of this is regretted. Essex Police now have the lead."
The RAF confirmed the aircraft was a Russian-made Antonov An-26.
In a tweet it apologised if crews had "startled people" but added that jets only went supersonic over land when absolutely necessary.
In a statement, Essex Police said military jets were deployed on a precautionary basis when a Lithuania-registered cargo plane was diverted to Stansted.
It said: "This was due to a loss of communication with the aircraft. The aircraft landed safely."
Police said all three people on board had been spoken to and it was established everything was in order.
The reason for the short loss of communication was due to a change in airspace jurisdiction, police added.
Officers said they were not investigating the incident and the aircraft would be able to continue its journey to Birmingham when ready.
