A light aircraft was also seized in Longford.
120 kilogrammes of cocaine, with an estimated street value of €8.4 million, has been recovered in Westmeath.
Two vehicles were intercepted by gardaí at 6 o'clock yesterday evening at two locations in the Lough Owel area.
Several communication devices were also found, and a series of follow up searches led to a light aircraft being seized in Longford.
Two males, age 54 and 40 years, have been arrested on suspicion of drug trafficking and are currently being detained.
Former Assistant Garda Commissioner, Pat Leahy, says it's a good day for Gardai and communities around the country:
The seizure occurred as a result of ongoing investigations targeting drug related organised crime activity by personnel attached to the Garda National Drugs & Organised Crime Bureau supported by other national units.
